Select the verb form that correctly completes this sentence. tú llegar a tiempo y empezar con el trabajo. debes debe debo debemos

The verb form that correctly completes this sentence is "debes".

Explanation: The verb that fills in the blank must be conjugated in the second person because the pronoun "tú" indicates second person. In Spanish, the second person in verbs is usually signaled by an "-s" at the end of the verb. In that way, the second person verb among the options provided is "debes"; therefore, "debes" is the verb form that fills in the blank. In contrast, "debe" is used for third person, "debo" for first person singular, and "debemos" is used for first person plural.
