Answer :

 

-lock-

So, the correct answer is (B) : Both assertion (A) and reason (R) are true but  reason (R) is not the correct explanation of  assertion (A). 

Explanation :

  • Assertion (A) : Geological processes of mineral  formation is slow . The rates of replenishment are infinitely small in comparison to the present rates of consumption.so, this is true.
  • Reason (R): Minerals resources are consumed way quickly than they are formed,as they are finite and non renewable.so, this is also true.
  • But, the Reason for the Assertion is False , because (A): Geological processes of mineral  formation happens over a very long geological time and is a natural process.

Thus,

  • Assertion is true
  • Reason is also true
  • But Reasoning is not the correct explanation for Assertion

So, the correct answer is (b)
