On winter evenings, a haze of smog `ul"hang in"` Delhi.

Options

A. is hanging over
B. hangs over
C. hangs up
D. No substitution required

Answer

B

Explanation

According to the "Subiect-Verb Agreement Rule", A haze of smog is considered as a singular subject and it will take .hangs. as a singular verb. Hang up means to delay or terminate a conversation. However, we use Hangs over to show that something bad is hanging above the other thing like the threat of terroism is still hanging over us. So, the preposition Over will be used with the verb hang to show how the haze of smog covers delhi in winter evenings.
