Hey mate , here is your answer. Hope it helps you .

Have.

Explanation:

How to use Have

Have is the conjugation of to have that’s used when:

speaking in the first person (I, we)

speaking in the second person (you)

speaking in the third person plural (they)

Take, for example, the following sentence: “They have two dogs.” Here, have is the correct choice because the subject (they) is a third person plural pronoun.

How to use has

Has is the conjugation of to have that’s used when:

speaking in the third person singular (he, she, and it).

This example from And the Mountains Echoed by Khaled Hosseini shows has used with a third person singular pronoun (he): “He has a slender nose, a narrow mouth, and tight blond curls.”

Bear in mind, this use of have and has only really applies when you’re speaking in the present tense (describing events that are currently happening.)
