Answer 2

The correct answer would be the nucleus.

Prokaryotic cells are the primitive cells which lack membrane-bound cell organelles such as a nucleus, Golgi apparatus, mitochondria et cetera.

A nucleus is a membrane-bound cell organelle which contains the genetic material of the eukaryotic cells.

In prokaryotic cells, the genetic material is kept floating in the cytoplasm in the region termed as the nucleoid.

Other cell organelles like a cell membrane, ribosome, genetic material or chromosome, and cytoplasm are present in both prokaryotic as well as eukaryotic cells.
