Directions: In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'. This happened (A) / just exactly (B) / five years ago (C) / when I was in Mumbai. (D) No error (E)

Step-by-step solution

In some specific context, we use the adverb 'just' to emphasize that something is happening or has happened at exactly the moment that you are talking about. In this sentence, use of the adverb 'exactly' beside 'just' is redundant and hence must be removed to make it a grammatically correct sentence. Hence, option B is correct.
