Answer:
The right answer is, Almorcé.
* Yo almorcé en la cafetería.
Step-by-step explanation:
Because they ask us to conjugate the veb in the past tense, which indicates actions that are carried out in the past tense and have not yet defined their end in the present, taking into account the above, the person, number and gender in the sentence must be identified to conjugate the verb in a logical way and agree with what is expressed.
