Correct option (c) 2 polar nuclei + 1 male gamete nucleus
Explanation :
During the event of double fertilization in angiosperms, the second male gamete fuses with the two haploid polar nuclei or diploid secondary nucleus of the central cell to form a triploid primary endosperm nucleus (PEN). This second fertilization is called vegetative fertilization.
