Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The catalyst does not alter the equilibrium constant.
For the catalysed reaction and uncatalysed reaction $Δ H$ remains same and equilibrium constant depends on $Δ H$ .
When catalyst is used, the equilibrium is achieved faster but the value of the equilibrium constant remains unchanged.
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
