The subject is who.
The subject is the noun that performs the action (verb) of the sentence. An object in a sentence is the noun that the action is performed upon. Example: I wrote a book. "I" is the subject; "wrote" is the verb; "book" is the object.
The subject is "book" or "a book"
The simple subject in the sentence "This book I must have for my report" is "book." The word "this" functions as a demonstrative adjective modifying "book," but the core subject is simply "book," which indicates what the sentence is about.
