✅ The analogy establishes a relationship where the first word is a worker, and the second word is a primary, specific tool they use to perform their craft or profession.

An Artist uses a Brush as a fundamental tool to create art.

Similarly, a Plumber uses a Wrench as a primary tool for their work, such as tightening or loosening pipes and fittings.

❌ A Singer's primary instrument is their voice; a Microphone is an amplifying device, not the fundamental tool for creating music itself, as the voice is.

❌ A Pilot operates an Airplane, but the airplane is the vehicle or object of their work, not a handheld tool used by them in the same direct way a brush is used by an artist.

❌ A Tailor works with Fabric, which is the material they manipulate, not a tool; a tailor's actual tools include needles, scissors, or a sewing machine.

✅ The first pair, "Plumber : Wrench," establishes a relationship where a worker (Plumber) uses a specific, essential hand tool (Wrench) to perform their primary craft or task (repairing pipes).

The correct answer, "Artist : Brush," maintains this exact relationship, as an Artist uses a Brush as an essential hand tool to create their primary work (painting).

❌ Option B, "Teacher : Chalkboard," is incorrect because while a teacher uses a chalkboard, the chalkboard is more of a display medium or piece of classroom equipment rather than a direct, hand-held tool like a wrench or brush.

❌ Option C, "Chef : Oven," is incorrect because an Oven is a large piece of cooking equipment or an appliance, not a direct, hand-held tool that a chef would use in the same manner a plumber uses a wrench.

❌ Option D, "Author : Book," is incorrect because a Book is the product of an author's work, not a tool they use to create; an author's tools would typically be a pen, keyboard, or computer.

✅ The analogy establishes a relationship where the first term is a worker and the second term is a primary tool that worker uses to perform their specific craft or task.

A Carpenter uses a Hammer as a fundamental tool to shape, fasten, or work with wood.

Similarly, a Sculptor primarily uses a Chisel as a key tool to carve, chip, and shape materials like stone, wood, or ice.

❌ Canvas is a surface for painting, not a direct tool for shaping used by a sculptor.

❌ A Brush is a tool used by painters for applying paint, not by sculptors for carving.

❌ An Easel is a stand used to support a canvas or artwork, typically for painting, and is not a direct shaping tool for a sculptor.

✅ The analogy establishes a relationship where the second term is the primary cutting tool used by the worker in the first term to perform their core task.

A Carpenter primarily uses a Saw for cutting materials in their profession.

Similarly, a Surgeon's primary cutting instrument during an operation is a Scalpel, which is used for making precise incisions.

❌ A stethoscope is a diagnostic tool used by doctors to listen to internal sounds, not a cutting instrument used by surgeons.

❌ Forceps are grasping or clamping tools used by surgeons to hold tissue or objects, not for cutting.

❌ Anesthetic is a substance used to induce unconsciousness or numbness, not a physical cutting tool.

✅ The relationship established is that of a specific worker and the primary, often hand-held, tool essential for their core task.

✅ A Carpenter uses a Hammer as their fundamental tool to build and shape materials.

✅ Similarly, a Surgeon uses a Scalpel as their essential, precise tool for performing operations.

❌ Option A is incorrect because a canvas is the material an artist works on, not their primary tool (which would be a brush or chisel).

❌ Option B is incorrect because a kitchen is a chef's workplace, not a specific tool used (a tool would be a knife or whisk).

❌ Option D is incorrect because a blackboard is a piece of equipment for teaching, not a direct, hand-held implement wielded by the teacher for a physical task in the same direct sense as a hammer or scalpel.
