Analogy — “Iron : Copper : Zinc”. Choose the option that is from the same category (chemical element/metal).

Introduction / Context:Iron, copper, and zinc are metallic elements. We must select an option from the same category.

Given Data / Assumptions:

• Focus on “metallic element.”

Concept / Approach:“Silver” is a metal (Ag). Carbon is an element but typically non-metal; ceramic and plastic are material classes; coke is a fuel/carbon form.

Step-by-Step Solution:

Verification / Alternative check:Chemical classification confirms silver as a metal.

Why Other Options Are Wrong:They are non-metals or composite materials.

Common Pitfalls:Confusing element vs compound vs material class.

Final Answer:Silver
