- B. FSH acts on interstitial (Leydig) cells
- C. LH (ICSH) acts on Sertoli (nurse) cells

Frequently asked questions
Are these official NEET 2017 Biology Reproduction PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2017 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
