Model Answer
(B) Both (A) and (R) are true, but (R) is not the correct explanation of (A).
Minerals are indispensable as everything from pins to ships is made from them. All living things do need minerals, but this alone does not explain why minerals are indispensable to all human life and industry.
Explanation
- (A) is true: the textbook states "Minerals are an indispensable part of our lives. Almost everything we use… are made from minerals."
- (R) is true: the textbook section "All living things need minerals" confirms this.
- However, (R) explains only the biological need for minerals, not the broader industrial, infrastructural, and everyday use that makes (A) true. So (R) is not the correct explanation of (A). Hence option (B).
