Answer:
Imperative
Explanation:
The imperative mood is a grammatical mood used to sed to give a command, an instruction, a piece of advice, or to make a request. This mood always addresses the second person (plural or singular), does not directly state the subject of the sentence (the subject is implied most of the time) and uses the base form of a verb. The sentence "Be on time!" is in the imperative mood because it expresses a command or an instruction directed to the second person (to "you") and uses the base form of the verb "to be:" "Be."
