A) No membrane is surrounding the genetic material.

The term "primitive nucleus" refers to a nucleus that lacks a distinct membrane surrounding its genetic material. In this context, "primitive" indicates a basic or less developed state, and "nucleus" refers to the cellular organelle that contains the genetic material (DNA) in eukaryotic cells. In more advanced eukaryotic cells, such as those found in plants, animals, and fungi, the nucleus is surrounded by a double membrane called the nuclear envelope. However, in certain organisms or cell types, the nucleus might have a more primitive structure where there is no membrane separating the genetic material from the rest of the cell's cytoplasm.
