Eukaryotic describes cells that are

• A. Lack a nucleus
• B. Contain a membrane-bound nucleus
• C. Are always multicellular
• D. Are prokaryotic

Answer: (B)

Eukaryotic cells are defined by having a nucleus that is enclosed by a membrane, along with other membrane-bound organelles. The nucleus keeps genetic material separate from the rest of the cell, housed inside a nuclear envelope. This distinction is why the correct description is that eukaryotic cells contain a membrane-bound nucleus. Lacking a nucleus describes prokaryotic cells, not eukaryotic ones. Saying eukaryotic cells are always multicellular is incorrect, since many are unicellular (like yeast or certain protists). Saying they are prokaryotic is simply the opposite of what they are.
