Solution

The correct option is D Assertion is incorrect but Reason is correct
22.4 L of ethane $(C_{2} H_{6})$ at S.T.P contains 6 moles of hydrogen atoms or 3 moles of hydrogen molecules. So the assertion is incorrect.

One mole of hydrogen molecules at S.T.P occupies 22.4 L volume which is correct.

So the assertion is incorrect but the reason is correct.
