Explanation:

To determine which cell type has membrane - bound organelles, we analyze each option:

• Option A: Prokaryotic cells do not have membrane - bound organelles. Their genetic material is not enclosed within a nucleus, and other organelles like mitochondria or endoplasmic reticulum are absent.
• Option B: Eukaryotic cells are characterized by the presence of membrane - bound organelles. The nucleus, which holds the genetic material, is surrounded by a nuclear membrane. Additionally, there are organelles such as mitochondria, Golgi apparatus, and endoplasmic reticulum, all of which have membranes.
• Option C: The term “Nucleokaryote” is not a recognized cell type in standard cell biology classification.
• Option D: Since prokaryotes lack membrane - bound organelles, not all cell types have this structure.

Answer:

B. Eukaryote
