Read this sentence to find out whether there is any error in it. The error, if any, will be in one part of the sentence. The alphabet number of that part is the answer. If there is no error, then the answer is (d). He began his discussion by pointing over (a) that men and women (b) had different biological functions. (c) No error (d)

Step-by-step solution

Here, part (c) is incorrect and needs correction. 'Have' should be used instead of 'had' because we use the past simple for past events or actions which have no connection to the present. We use the present perfect for actions which started in the past and are still happening now OR for finished actions which have a connection to the present. Plus, the part after that is a fact so it should be in present tense. Hence, (c) is the right answer choice.
