Explanation:

The dissolution of ANY IONIC SALT (typically in water) involves the formation of new substances, aquated ions, and the making and breaking of strong chemical bonds. And thus, BY DEFINITION, dissolution of ANY salt in water is A CHEMICAL CHANGE.

For the purposes of your question, they are looking for answer #(d)#. Fluoride is the conjugate base of a weak acid, and thus in water will produce hydrolysis:

#F^(-) + H_2O(l) rightleftharpoons HF(aq) + HO^-#
