Answer
A is true but R is false.
Explanation — Water dissolves many substances, forming aqueous solutions. Not only solids but gases and other liquids can also dissolve in water to a large extent. For this reason, water is called a universal solvent. Hence the assertion (A) is true.
It is true that nobel metals and glass does not dissolve in water but all compounds do not dissolve in water; for instance, many nonpolar substances, such as oils, do not dissolve in water. Hence reason (R) is false.
