• C. true nucleus
• D. none of the above

Answer 1

The correct option is A nucleoid

The nucleoid is a primitive nucleus which contains the single DNA which is coiled around itself. This genetic material is not enclosed by the nuclear membrane. This is a characteristic feature of the prokaryotes.

Karyon is the synonym of nucleus.
A true nucleus has a nuclear membrane surrounding the nucleoplasm in which we find the DNA condensed into chromosomes and the presence of a nucleolus.
