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

Prokaryotic cells lack membrane-bound organelles and well-organized nucleus. The nuclear membrane is absent in a prokaryotic cell. The nuclear membrane is a double membrane layer which surrounds the nucleus. It is made up of lipids, that encases the genetic material.

Hence, the correct answer is 'Nuclear membrane'.
