Options

A. 1 He is a university professor
B. 2 but of his three sons
C. 3 neither has any merit.
D. 4 No error

Answer

3

Explanation

none will replace neither because - neither is used for not one or the other but none is used for not any (more than two) Look at the examples given below: None of these pens work/works. We have three sons but none of them lives/live near by. Hence, none has any merit is the right usage
