Write down their configuration first.
O => 1s2 2s2 2p4
S => 1s2 2s2 2p6 3s2 3p4
Cl => 1s2 2s2 2p6 3s2 3p5
F => 1s2 2s2 2p5
Therfore the most electron gain enthalpy element is Cl.
S would have more gain enthalpy than O.

Cl>F>O>SBecause from top to bottom electron gain enthalpy decreases and from left to right increases in a period
