D
Solution:
In hexaploid male plant 6n chromosomes are present. It produces triploid gametes. Diploid female gamete and diploid polar nuclei are produced by tetraploid female plant. Endosperm is a triploid tissue. It is produced by triple fusion between one male gamete and two polar nuclei.
Triple fusion= 2 polar nuclei +1 male gamete = 2(2n) + 3n =4n+3n =7n
