Solution

The correct option is C Pentaploid
A diploid (2n) male angiospermic plant is crossed with tetraploid (4n) female plant. Endosperm of seed will be pentaploid as female gamete will undergo meiosis and form 2n gametes. These 2n gametes will fuse with n male gamete along with 2n polar nuclei. So the ploidy will be pentaploid. So, the correct option is D.
