Choose the most suitable option to replace the highlighted part of the sentence:
A part of the rural population are migrated to the cities.
Show answer & explanation
Correct answer: D
Explanation
The correct option is (D) because the subject 'A part of the rural population' is a singular noun phrase, as 'population' is treated as a collective noun here. Therefore, it requires a singular verb 'has' instead of 'are' or 'have'. Additionally, the phrase should be in the active voice ('has migrated').
