Question

Assertion is correct but Reason is incorrect.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.

Option (D) is correct.

Fluoride is very electronegative, and thus the bonding forces between Ca2+ and each fluoride anions are very strong, they are tightly held together in the crystal form. A few water molecules do not have enough strength to get in between and dissolve it. Thus, CaF2 is insoluble in water but more ionic, having high lattice energy due to small size of F−.
