Choose appropriate option to fill in the blank:I was born in London but I ___________ (grow) up in the north of England.

The correct answer is: grew.

The sentence is in the past simple tense, so the verb “grow” should also be in the past simple tense. The other options are not in the past simple tense.

• “Have grew” is not a correct verb form.
• “Am growing” is in the present continuous tense, which is not appropriate for this sentence.
• “Had grown” is in the past perfect tense, which would be appropriate if the sentence were about something that happened before another event in the past. However, the sentence is simply about where the speaker grew up, so the past simple tense is correct.
