Eukaryota is a varied domain of creatures whose cells have a nucleus, and its members are referred to as eukaryotes.
Eukaryotes include all animals, all plants, all fungi, and many unicellular creatures. They are a part of the Eukaryota or Eukarya group of organisms, one of the three categories of life.
Animals, fungi, plants, and protists all have eukaryotic cells. DNA is typically housed in the nucleus, an organelle that is encircled by a membrane known as the nuclearenvelope.
A nuclear membrane is present in eukaryotic cells. It has a cell wall, mitochondria, and Golgibodies.
It also has cilia and flagella, which are locomotory organs. The DNA in the nucleus contains all of the genetic data.
Thus, the correct option is B.
