Question

1. ¿a qué hora juegan?

en mi casa.
al mediodía.
mi padre.

Explanation:

The question "¿A qué hora juegan?" asks "At what time do they play?". We analyze each option: "En mi casa" (At my house) answers a location question, "Mi padre" (My father) answers a who question, while "Al mediodía" (At noon) answers a time question, which matches the "qué hora" (what time) query.

Answer:

B. Al mediodía. (Note: Assuming the middle option is labeled as B for clarity; if we consider the options' positions, it's the middle option "Al mediodía".)
