Given below are two statements:
| Assertion (A): | Electron gain enthalpy becomes less negative as we go down a group. |
| Reason (R): | The size of the atom increases on going down the group and the added electron would be farther from the nucleus. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
