Select the most appropriate option to fill in the blank.

She had won the match when we ______ the venue.

reached

The correct answer is reached.

The sentence is in the past perfect tense, which is used to describe an action that happened before another action in the past. In this case, the action of "reaching the venue" happened before the action of "she had won the match."

The other options are incorrect.

• Reach is the simple past tense of the verb "to reach." It is not appropriate in this sentence because it does not indicate that the action of reaching happened before the action of winning the match.
• Had been reaching is the past perfect progressive tense of the verb "to reach." It is also not appropriate in this sentence because it indicates that the action of reaching was ongoing before the action of winning the match.
• Are reaching is the present tense of the verb "to reach." It is not appropriate in this sentence because it does not refer to an action that happened in the past.
