(A) In angiosperms,the endosperm is formed by the fusion of one male gamete $(n)$ with two polar nuclei $(n+n)$ or a secondary nucleus $(2n)$. Given: Female plant is diploid $(2n)$,so the polar nuclei are $n$ each. The secondary nucleus is $2n$. Male plant is tetraploid $(4n)$,so the male gamete produced is $2n$. Endosperm ploidy = (Male gamete) + (Secondary nucleus) = $2n + 2n = 4n$ (Tetraploidy).
