Which of the following is an organism whose cells each contain a membrane
bound nucleus?

D. Eukaryote

Explanation:

An organism that has membrane-bound organelles will have more complex organelles like mitochondria, Golgi apparatus, and ER. These are known as Eukaryotes. Additionally, they will have a nucleus that has the DNA coiled inside. Prokaryotes do not have membrane-bound organelle and the DNA floats in the cytoplasm. Most plants and animals are eukaryotes and all multicellular organisms are too.
