Answer:

Therefore, the correct answer is D: CH3COONA, C6H12O6, and C₂H5OH all exist in aqueous solutions in the form of molecules.

Step-by-step explanation:

All of the substances listed exist in aqueous solutions in the form of molecules.

Aqueous solutions are solutions in which the solvent is water. Substances in aqueous solutions can exist as molecules, ions, or a combination of both.

C6H12O6, also known as glucose, exists as a molecule in an aqueous solution.

C₂H5OH, also known as ethanol, exists as a molecule in an aqueous solution.

K3PO4, also known as potassium phosphate, exists as ions in an aqueous solution. The potassium cation (K+) and phosphate anion (PO4^3-) are separate ions in solution.

CH3COONa, also known as sodium acetate, exists as ions in an aqueous solution. The sodium cation (Na+) and acetate anion (CH3COO^-) are separate ions in solution.
