Answer
Both A and R are true but R is not the correct explanation of A.
Explanation— Hydrogen chloride has sour (acidic) taste. Hence, the assertion (A) is true.
HCl is highly soluble in water and it can be proved by performing Fountain experiment. Hence, the reason (R) is true.
However, the high solubility of HCl in water doesn't relate to its taste, Hence, the reason (R) is not the correct explanation of assertion (A).
