Answer:
A) vacuole
Explanation:
Vacuole is the cell organelle which is smaller in size in animal cells as compared to plant cells. In plants vacuoles are meant for long term storage of water, food and waste products because the waste products cannot be eliminated readily from the plant cells due to the hindrance offered by cell wall. Apart from this, in plant cells vacuoles help in maintaining the the cell shape in collaboration with cell wall. But, in animals they mainly serve the function of storage. In pant cells, usually there is one single very large vacuole which is located in the center of the cell whereas in animals there are many small vacuoles which are scattered all over the cytoplasm of cell.
