In the following questions a statement of Assertion (A) followed by a statement of reason
(R) is given. Choose the correct option out of the choices given below each question.

Assertion (A) : Electron gain enthalpy becomes less negative as we go down a group.

Reason (R) : Size of the atom increases on going down the group and the added electron would be farther from the nucleus.

(i) Assertion and reason both are correct statements but reason is not correct explanation for assertion.

(ii) Assertion and reason both are correct statements and reason is correct explanation for assertion.

(iii) Assertion and reason both are wrong statements.

(iv) Assertion is wrong statement but reason is correct statement.

(iv) Assertion is wrong statement but reason is correct statement.

Electron gain enthalpy becomes less negative as we go down the group as on going down the atomic size increases due to the increase in the number of shells which makes electron farther.
