Answer:
This is a simple sentence with an understood subject (B)
Explanation:
The sentence above is an imperative sentence expressing a command. In English, the subject of a command, order, or suggestion is usually left out of the sentence and is said to be the understood subject. You are the person being directed; in fact, if you add the 2nd person singular pronoun, the sentence still has the same meaning. The only difference is that it will contain an overt subject (see 1).
