Which sentence contains a word or phrase that requires a hyphen? a) the former tenants broke the microwave. b) when i get home i will unload the dishwasher. c) the clothes in my suitcase need to be repressed. d) automatic dishwashers are very practical and convenient.

C) The clothes in my suitcase need to be repressed.

In this sentence, the author is trying to convey the idea that his clothes are wrinkly, as they were stored in his suitcase. Therefore, they need to be pressed again.

Instead, the verb is written as "repressed," which means "to hold down or control," and is not the meaning the sentence is trying to convey.
