The best answer is C.
Plant cells are surrounded by a cell wall and have chloroplasts whereas animal cell do not.
The cell wall is a covering that is rigid whose main purpose is to protect the cell and give structural support as well shape to the plant cell. The equivalent of a cell wall in animal cell is the cell membrane, which has distinct differences from the plant cell wall.
Chloroplasts are plant cell organelles which carry out photosynthesis by which plants make their own food. These are absent from animal cells because animals do not make their own food, they ingest it from external sources.
