- A. We saw many surfers at the beach. → many here is an adjective modifying “surfers,” not an indefinite pronoun.
- B. Each candidate must give a short speech. → each is also acting as an adjective modifying “candidate.”
- C. A few of my friends are coming over. → a few here is an indefinite pronoun (standing for an indefinite number of friends). ✅
- D. Most students are looking forward to summer vacation. → most is modifying “students,” so it functions as a determiner, not a standalone pronoun.
👉 The correct answer is: C. A few of my friends are coming over.
