<span>The answer is C. This is because the discovery of
the cell and its organelles began with the discovery of the microscope in the
17th century. As powerful microscopes were developed over time, the
cell organelle become discover-able by different scientists. As other developments emerged, they enabled tagging of
elements, hence monitoring of biochemical pathways also became possible.</span>

Answer:
The correct answer would be c) food molecules.
A vacuole is a membrane-bound cell organelle present usually in the center of the plant cell.
It contains a high amount of water as it plays important role in maintaining the turgor pressure of the cell.
In addition, it contains a high amount of ions (such as K⁺, Mg²⁺, Ca²⁺), food molecules (such as glucose, sucrose, fructose), organic acids (such as malic, tartaric, quinic) and waste material.
