Question

He... at seven thirty. gets up. get up. get ups​

Answer 1

He gets up at seven thirty.

Answer 2

The correct form is "He gets up at seven thirty." This sentence is in the present tense and describes a habitual action, so you use "gets up" to indicate that he regularly gets out of bed at that time. "Get up" is the base form of the verb, and "get ups" is not a correct form in this context.
