Question
Which one does not belong to the Group?
- A. Mica
- B. Zinc
- C. Water (Correct answer)
- D. Iron
Correct Answer
Option C — Water
Detailed Solution & Explanation
The correct answer is Water.
Key Points
- Mica, zinc and iron are all minerals or metals extracted from the earth in solid form.
- Water is a liquid compound, not a mined mineral, which makes it the odd one out.
Additional Information
- Mica is a non-metallic mineral valued for electrical insulation; India, and Jharkhand in particular, is a leading producer.
- Zinc and iron are metallic minerals; zinc is used chiefly for galvanising iron against rust.
- Minerals are usually classified as metallic (iron, copper, bauxite, zinc), non-metallic (mica, limestone, gypsum) and energy minerals (coal, petroleum).
