The correct option is A Vacuoles
In a plant cell, the vacuoles are large and centrally placed organelle. Vacuoles typically contain salts, sugars and sometimes proteins and have a variety of secretory, excretory and storage functions.The vacuole may also be involved in the breakdown of old organelles or macromolecules and then recycling the products back to the rest of the cell. Thus, they are in large number in a cell adapted for waste storage and disposal.
So, the correct answer is option A.
