Answer 1

Correct answer is (d) Absolute or intrinsic solubility

For explanation I would say: Absolute or intrinsic solubility is defined as the maximum amount of solute dissolved in a given solvent under standard conditions of temperature, pressure, and pH. It is a static property. Dissolution rate is the amount of a solid substance that dissolves into solution under given conditions.
