Answer: M. de Tréville is the name of the captain in the novel The three musketeers
The simple subject is the main word of the subject, without any adjectives or modifications, one that would be enough to form a correct sentence; and the complete subject is one with all the adjectives and modifiers.
For example: B:
Dinosaurs: simple subject
<span>Large and small dinosaurs: complete subject.
In option C </span>the simple subject is the complete subject: "Cory"
I believe the answer is D.
This makes zero sense ... sorry the question is not clear i do not get it
