Since the question says Aposporously then there will be no meiotic division so Male pollens instead of having 2n will have 4n ploidity nd female ovum will also have same no. of ploidity ie. 2n so the embryo will have 6n ploidity
so the answer should be none of these
so the answer should be none of these

The condition given in the question is diploid female is crossing with a tetraploid male.
It means that female is in 2n condition whereas male is in 4n condition. After meiosis reduction the gametes formed were n condition of female and male is in 2n condition. When these two gametes fuses, they tends to form zygote which is triploid (3n) in condition.
For endosperm formation triple fusion occurs in which “two polar nuclei and one male gamete” fuses with each other. Here the polar nuclei are in haploid (n) condition and male gamete is in diploid (2n) condition. Hence the fusion is n+n+2n = 4n. Hence the resultant is tetraploid male.
