Answer:
Option a, The salt is the solute and the water is the solvent.
Step-by-step explanation:
A solution consists of two components:
The component of the solution that dissolves in another substance is solute whereas the component of the solution which dissolves a substance is solvent.
Amount of solute is less as compared to solvent.
In the given case, amount of salt (NaCl) is less as compared to water (150 g).
So, salt is the solute and water is the solvent.
