Question

Complete the sentence with the best option from those given below.

Neither of them has done _____ work.

• A. their
• B. theirs
• C. his
• D. them

Answer 1

The correct option is C his

'Neither of them' can be followed by a singular or plural verb. Depending on the verb in this sentence "has", it is indicated that the person must be singular. From the options, 'his' is in the third person singular narrative. Hence option C is correct. ('his' is a possessive adjective)
'Their' is in the third person plural, whereas the required form must be a third person singular. Same goes for 'theirs' and 'them'. Hence options A, B and D are incorrect.
(their is a possessive adjective, theirs is a possessive pronoun and them is an object pronoun.)
