Answer 1

Answer: (A), (B), (D)

The correct options are
A Minerals are overexploited by humans.

B Increase in the population of humans has increased the needs of minerals.

D Efficient methods of mining and smelting must be practised to avoid wastage of minerals.


Minerals can be conserved in three ways - recycling, avoiding wastage and usage of substitutes. Increase in human population has led to a rise in the demands of minerals. Minerals are non-renewable; once consumed, they cannot be replenished for a long time.
