Final answer:
The correct reflexive verb in the conditional tense to fill in the blank is 'se levantaría'.
Step-by-step explanation:
The correct reflexive verb in the conditional tense to fill in the blank is D. se levantaría. The sentence translates to 'At six o'clock every day. If Luz didn't have to go to school, she wouldn't get up.'
The verb 'levantarse' means 'to get up' and when conjugated, it becomes 'se levantaría' in the conditional tense. The reflexive pronoun 'se' is used to show that the action of getting up is being done to oneself.
In this case, since Luz doesn't have to go to school, she wouldn't have the obligation to get up early, so she wouldn't get up at six o'clock.
