Solution

The correct option is D Zero
Prothallial cells are the vegetative cells that are present in the gymnosperms male gametophytes. These are sterile cells and are present along the antheridial cell which develops into the generative cell and the tube cells.
So, as they are present only in gymnosperms and completely absent in angiosperms, there are 0 prothallial cells in the male gametophytes of the angiosperms.
So, the correct option D. Zero.
