Question

Choose the correct verb to complete the sentence: 'The number of students who have opted for the elective course ___ increased significantly this year.'

• A. have
• B. having
• C. has
• D. were

Hint:

Check whether the sentence begins with "The number of" or "A number of", since these two near-identical phrases take opposite verb forms.

Answer 1

The Correct Option is C

'The number of' takes a singular verb, while 'A number of' takes a plural verb. Since the subject here is 'The number', the verb must be singular, i.e., 'has'. Correct option: 3.
