The example of an imperative sentence is D. Please remember to get the dry cleaning.
An imperative sentence is there not to inform, but to order somebody to do something. Although using the word please makes it sound less of an order, you are still telling somebody to do something - in this case, not to forget to get the dry cleaning. 
A is an interrogative sentence, whereas B and C are declarative.
