Answer:
The correct answer is: "Ve".
Step-by-step explanation:
In Spanish is used the imperative mode for giving commands, which is only used for the second person singular (tú), the second person plural (vosotros), and its courtesy persons respectively (usted, ustedes).
Normally, the way to conjugated a verb in the affirmative imperative for the second person singular is to use the normal conjugation used in the third person singular for the indicative present. But as the verb "ir" is irregular, then the verb most be conjugated as it follows: "VE". It do not goes with the regular conjugation rule, therefore the conjugation is not: "va".
