Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Alkaline earth metal salts are less soluble in water than the corresponding alkali metal salts,because Alkaline earth metal cations possess high lattice energy due to their smaller size and higher charge. So, both assertion and reason are correct and reason is the correct explanation for assertion. Hence option A is correct.
