The correct option is A \N
A vacuole is a cell organelle used to store waste materials, store nutrients, excess salts etc. and usually big and more in number in mature cells. Meristematic cells are mainly concerned with cell division and the primary function is mitosis. These cells use up nutrients and energy continuously and do not store materials inside it, therefore they do not require a vacuole. Vacuoles when present are small and lesser in number.
