Answer:
saldría.
Step-by-step explanation:
The sentence is in the conditional tense, expressing a hypothetical situation or a condition that is contrary to fact. The missing word should be conjugated in the first person singular (yo) to match the subject of the sentence.
The verb "salir" means "to go out" or "to leave," so the correct option is "saldría," which is the conditional form of "salir" for the first person singular. The sentence translates to "I would go out of the house, if I didn't have to cook."
