Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
As we move down the group atomic size increases due to increase in the outer most shells.
Hence as we move down it will be easier to remove electron as we do not need much energy. Hence in a group I.P decreases.
Ionization potential is defined as the amount of energy required to remove an electron from the outer most shell in it's gaseous state.
Option A is correct.
