Assertion (A): Manganese is mainly used in the manufacturing of steel and ferro- manganese alloy.

Reason (R): It is also used in manufacturing bleaching powder, insecticides and paints.

 

Answer :

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) : Manganese is mainly used in the  manufacturing of steel and ferro- manganese alloy. Nearly 10kg of manganese is required to manufacture 1 tonne of steel. So this is true.
  •   Reason (R): It is also used in manufacturing  bleaching powder, insecticides and paints. So, this Is also true.
  • But R is not the correct explanation for A, because manufacturing of Bleaching powder, insecticides and paints is not related to the manufacturing of steel and ferro manganese alloy.

Thus,

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

 So, the correct answer is (a)
