Answer: Option D
Answer: (d)Reading both the clauses of the sentence, we find that the sentence is about something that happened in past. The words “predicted” and “would come” in the second clause confirms this. The sentences of simple past take Verb’s 2nd form in writing main verb. With this way, two of our answers - (C) and (E), get cancelled to be the answer as they are in basic form of verb. The 2nd part of the sentence shows about the “prediction of exit polls”, which simply needs to have elections completed. With this, (D) Concluded fits perfect.
