The correct statement is D. This is an animal cell; the evidence is the cell membrane.
The cell membrane is a defining feature of animal cells, as it is the outermost layer that encloses the cell and separates it from the external environment. The cell membrane is selectively permeable, meaning it allows certain substances to pass through while preventing others from entering or leaving the cell. Animal cells also have other organelles, such as mitochondria, but these are not unique to animal cells and can also be found in plant cells. The presence of the cell wall, as in statement A, is actually a defining feature of plant cells, not animal cells.
