Fill in the gaps with the correct option. Chris ______ to be a travel agent.

The sentence requires a verb phrase that indicates a future intention or a plan. 'is going' is the correct present continuous form used for future arrangements or intentions. 'am going' is incorrect because the subject is 'Chris' (third person singular). 'will going' is grammatically incorrect; it should be 'will go'. 'goes' is the simple present tense, which is not appropriate for expressing a future plan in this context. Therefore, 'is going' fits best.

Chris is going to be a travel agent.
