Question

Choose the appropriate option to fill in the blank:

• A. Non-Ferrous minerals
• B. Igneous minerals
• C. Energy minerals
• D. Ferrous minerals

Hint:

Minerals are broadly classified into three groups: {Metallic minerals}, {Non-metallic minerals}, and {Energy minerals}. Coal and petroleum are common examples of energy minerals.

Answer 1

The Correct Option is C

Concept: Minerals are naturally occurring substances found in the earth's crust. They are generally classified into three main categories based on their properties and uses: Metallic minerals, Non-metallic minerals, and Energy minerals. Each category includes minerals that serve different purposes.
Step 1: Understand the given classification.
The diagram shows three groups of minerals:

• Metallic minerals — Example: Iron ore
• Non-metallic minerals — Example: Mica
• A third category represented by coal

Step 2: Identify the category of coal.
Coal is mainly used as a source of energy and fuel. Therefore, it belongs to the category of energy minerals.
Step 3: Select the correct option.
Since coal falls under energy resources, the missing category must be: \[ Energy minerals \] Hence, the correct answer is Option (C).
