Answer:
Yo no tuve tiempo para comprar la comida, pero la pedí por teléfono y el vendedor me la envió.
Step-by-step explanation:
Yo no tuve tiempo para comprar la comida, pero la pedí por teléfono y el vendedor me la envió. This means: I didn't have to to order the food but I asked for it over the phone and the delivery guy sent it to me.
Pedí is the preterite of the verb "pedir" conjugated in the first person singular. Option c. pedir is incorrect because it's the infinitive. Pedimos is the first person but plural. And in the sentence there aren't other people involved when making the call for the delivery. Pidió is the conjugation of the third person singular, so it's also grammatically incorrect.
