From the words or group of words lettered A to D, choose the word or group of words that best completes the sentence.

It's been smooth so far .............?

Answer Details

The best option to complete the sentence is "hasn't it." "It's been smooth so far" indicates a present perfect tense, meaning that an action started in the past and is still continuing until now. Therefore, the appropriate response should also be in present perfect tense. "Hasn't it" is the correct response, indicating a confirmation of the smoothness of the ongoing action. Option A, "hadn't it" indicates past perfect tense, which is not appropriate. Option B, "wasn't it" indicates past tense, which is not appropriate either. Option C, "isn't it" indicates present tense, which does not match the tense of the original statement.
