This question came in the Dhaka university admission test 2012-13
Q) Which of the following is correct?
(A) The jury are arguing among themselves.
(B) The jury is arguing among themselves.
(C) The jury has argued among themselves.
(D) The jury has been arguing among themselves.
According to this blog, collective nouns should be treated as if they are singular. So, (A) is wrong clearly. Funnily enough, my question bank says (A) is the correct answer.
To be honest, none of (B), (C), and (D) seem right to me. Probably, a better formulation is "The members of the jury is arguing/ has been arguing/ has argued among themselves."
Anyhow, if I must pick one answer from the three options, I have a problem. All three options, (B), (C), and (D), contain singular verbs. So, I'm not sure which one to pick as the correct answer.
Now that I think about it, probably, the question setter thinks that the correct answer is (A) as it is the only answer with a plural verb.
Which is the actual correct option of the 4 options?
