Question

Tom is one of the boys who _________always on time.



a. Is
b. are
c. was
d. none of the above​

Answer 1

Tom is one of the boys who was always on time

Answer 2

Tom is one of the boys who is always on time.

• In this case, the sentence makes use of the term 'one of the'.
• While using 'one of the', the noun following it is always written in plural while the verb after that is singular.
• Here, as we can see one of the boys is written, (the plural form of noun boy). Hence the verb following it will be singular. Thus, the answer should be 'is'.
• Also, the action here is to be on time. This action is performed by one boy only, and not the group of boys. Thus, it will require a singular verb.
