Explanation / Answer

Solubility increases with rise in temperature. Hence when we add any solute in cold solvent its solubility decreases. Answer is option A and B. Now let's see why other options are not right:

B) adding salt (solute) to boiling water will always increase its solubility as temperature is high.

D) Addind marshmallows is just the physical mixing.
