Step-by-step explanation:
Let's analyze each answer choice.
A. Nucleus
- Houses the genetic material (DNA) and produces RNA
B. Cytoplasm
- Fills in space, keeps organelles in place, and chemical reactions occur here
C. Vacuole
- Stores substances, isolates toxins, helps with excretion
D. Chloroplast
- Photosynthesis occurs here
Based on the functions of each organelle, we can assume the best answer is C. Vacuole. Vacuoles store substances, so these organelles would hold water.
