Which one of the following structures is not found in a prokaryotic cell?

Dear student 

Prokaryotes are unicellular organisms so that they lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

Option B is correct choice.

Good Luck
