Answer:
answer C
Step-by-step explanation:
this is the near future tense, it directly translates to "they are going to watch a film". the way you know it is the future tense as it is the pronoun (eg. Je (meaning I) or, in this case, Ils) + the conjugated term for aller (eg. Vais (used for the pronoun Je) or, in this case, Vont) and then an infinitive (eg. Faire (meaning to do) or, in this case, Regarder).
