The husband shows his reluctance to go out stating he is tired, suggesting they eat _____.

The sentence indicates that the husband is suggesting an alternative to going out because he is tired. The phrase “eat at home” clearly communicates this intention, as it implies staying in rather than going out to a restaurant or other location. It directly follows the context of his reluctance, providing a logical solution that aligns with his feelings of fatigue.

The other choices do not fit naturally into the context. Saying "eat out" implies the opposite of what the husband is suggesting, while "too" lacks a complement to provide clarity in the sentence. The term "away" also does not convey the idea of being at home, as it suggests being elsewhere, which contradicts the husband’s reluctance to leave.
