JEE Main Chemistry question

Statement 1: Sulphur atom has higher electron affinity than oxygen. Statement 2: Oxygen is more electronegative than sulphur, that's why can hold electron better.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for AssertionCorrect
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (B)

Solution

Sulfur does have a higher electron affinity than oxygen (≈200 kJ/mol vs ≈141 kJ/mol) because oxygen's smaller size causes greater electron-electron repulsion toward an incoming electron — both statements are factually true. However, oxygen genuinely is more electronegative than sulfur, and if
