To answer this question, we simply need to insert the correct particle. Referring to the vocabulary list on pg. 105 of your Genki I textbook, we see that we use the particle ‘に’ with the verb ‘会う（あう）.’ In this sentence, our friend is the direct object, but ‘に’ is preferred. You can conceptualize that we use ‘に’ instead of ‘を’ because the verb ‘会う（あう）’ has the implication of movement toward a place, though there is no one reason for why ‘に’ is used. We could also use the particle ‘と’ for the nuance that both us and our friend are equally participating in the meeting, but ‘に’ is just as correct. The answer is ‘に.’

The answer is ‘を.’
