(D) The microspore of $Selaginella$ undergoes development to form a $13$-celled male gametophyte.This structure consists of $1$ prothallial cell,$8$ jacket cells (which form the wall of the antheridium),and $4$ primary androgonial cells (which eventually produce the antherozoids).Therefore,the correct composition is $1$ prothallial cell $+ 8$ jacket cells $+ 4$ androgonial cells.
