Select the grammatically correct sentence.

**The reasoning** The subject here is **"each"** — and "each" is *always* singular, even when followed by "of the students." The phrase "of the students" is just a prepositional phrase describing which group we're talking about; it doesn't change the subject. Since "each" is singular, it needs the singular verb **"has"**, not "have." Think of it this way: You're focusing on *one person at a time* — each *individual* student has their own book. **Why the wrong options tempt you** - **A & D:** "Students" is plural and sits right before the verb, so your brain screams "use *have*!" But remember: the true subject is "each," not "students." - **C:** "Having" isn't a complete verb — it's a participle. This creates a sentence fragment with no proper verb. **Quick takeaway** Whenever you see **"each," "every," "either," "neither,"** or **"none"** as the subject, treat it as *singular* — no matter what plural noun follows in a phrase.
