Read the sentence. For optimal health, eat plenty of fresh fruits and vegetables, _______________, and sleep at least seven hours a night. Which clause completes the sentence by creating parallelism?

The sentence gives two actions as commands: “eat plenty of fresh fruits and vegetables” and “sleep at least seven hours a night.” The missing phrase should also be a command, so “exercise regularly” keeps the verbs parallel. “Regular exercise” is a noun phrase, while the other choices do not match the sentence’s command structure.
