Answer:
Non, il ne l'a pas comprise.
Step-by-step explanation:
This is the correct answer because the question is asking whether Atil understood the conjugation of the verb "aller," so the appropriate response should include the correct conjugation of the verb in the answer. The correct form of the past participle of "comprendre" (to understand) is "comprise" in this context, and the correct form of the direct object pronoun "la" (referring to the conjugation of "aller") should be used. Therefore, the correct response is "Non, il ne l'a pas comprise."
