Solution

The correct option is C Assertion is correct but Reason is incorrect
Well know fact that sulphates of all elements are soluble except $S r$ , $B a$ , $P b (I I)$ . Calcium and silver are slightly soluble.
High hydration energy doesn't imply solubility. Hydration energy > lattice energy implies solubility.
