Answer & Solution

Correct Answer

(A) \(Cl\)

Step-by-step Solution

Detailed explanation

Electron affinity is the energy released when an electron is added to a neutral atom in the gaseous state. Among halogens, electron affinity is generally high due to the tendency to gain one electron. However, fluorine has a very small atomic size, so strong electron–electron repulsion in its compact 2p orbital reduces its electron affinity slightly.
