A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Prokaryotes do not have a true nucleus but possess all other types of organelles.

Detailed explanation-2: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Detailed explanation-3: -The major difference between the Prokaryotic and the Eukaryotic cell is the absence of the nucleus in the prokaryotic cell. The other three components: the cytoplasm, cell membrane and the ribosomes, are present in both Prokaryotic cells and Eukaryotic cells.

Detailed explanation-4: -Prokaryotes, by definition, are organisms in which the nucleus and other membrane-bound organelles are absent.

Detailed explanation-5: -Only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes-pro means before and kary means nucleus. Animals, plants, fungi, and protists are all eukaryotes-eu means true-and are made up of eukaryotic cells.
