Answer:

A nucleus. (Ans. B)

Explanation:

Prokaryotes are a unicellular organism that lacks a nucleus and other cell organelles due to the absence of internal membranes. The prokaryotic cell membrane is made up of phospholipids and the cytoplasm contains ribosomes, which carry out protein synthesis and a double-stranded DNA chromosome (which is circular in structure).

They are reproducing through asexual reproduction mainly through binary fission. They have various shapes, four basic shapes of bacteria are:

1) Cocci

2) Bacillus

3) Spiral bacteria

4) Vibrio
