Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The fluorides of alkaline earth metals are relatively less soluble than chlorides due to the small size of fluoride it has high hydration as well as lattice enthalpy than chloride but in some cases, the difference is greater for fluoride than chloride, hence the fluoride of group 2 metals are less soluble.
