MCQ
The cell which develops into endosperm, results from the fusion of
  • A
    two male gametes and the egg.
  • B
    two male gametes and two polar nuclei.
  • C
    one male gamete and two polar nuclei.
  • D
    a male gamete and the egg.

Answer

C. one male gamete and two polar nuclei.
Explanation:
Endosperm develops from primary endosperm cell (PEC) which is formed from the fusion of two polar nuclei of the central cell with a male gamete.
