The answer is the first one (A): Eukaryotes.

Explanation for each option: (A) Eukaryotes: Correct. Eukaryotic cells contain membrane-bound organelles, such as the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus. (B) Prokaryotes: Incorrect. Prokaryotic cells, such as bacteria and archaea, do not have membrane-bound organelles. Their cellular structures are simpler and lack a defined nucleus. (C) Prions: Incorrect. Prions are infectious proteins that do not have any cellular structure or organelles. They are simply misfolded proteins that can induce other proteins to misfold. (D) Viruses: Incorrect. Viruses are not considered living cells and do not have membrane-bound organelles. They consist of genetic material (DNA or RNA) enclosed in a protein coat and sometimes a lipid envelope, but they lack the complex structures found in eukaryotic cells.

Summary: Eukaryotes are the only option that contains membrane-bound organelles.
