Final answer:
In imperative sentences like 'Close the door behind you,' the subject is the implied 'you.' The correct option that reflects this and the complete predicate is D) 'Close the door behind / you,' with 'you' as the complete subject and 'Close the door behind' as the complete predicate.
Correct option is D. Close the door behind / you
Step-by-step explanation:
In the sentence "Close the door behind you," we have an imperative sentence where the complete subject is the implied pronoun "you", although it is not explicitly stated. The complete predicate in this sentence is "Close the door behind", which contains the imperative verb (command) 'Close' and the rest of the action being commanded. Therefore, the correct option that identifies the complete subject as 'you' and the complete predicate is:
you / Close the door behind
Option D) Close the door behind / you is the correct choice, which requires us to write 'you' as the subject for the imperative sentence and to underline this pronounce when identifying the complete subject.
