Answer (1)
The correct answer is: unless.The sentence should read: "My family will go on vacation unless my dad has to work during spring.""Unless" indicates an exception or a condition that would prevent something from happening. In this case, the family's vacation plans depend on the dad's work schedule.Hope it helped you!!
