Correct option is B

Perchloric acid is a mineral acid with the formula HClO4. It is an oxoacid of chlorine. Perchloric acid, a superacid, is one of the strongest Brønsted–Lowry acids. It provides strong acidity with minimal interference because perchlorate is weakly nucleophilic (explaining the high acidity of HClO4).

In the presence of perchloric acid, the given compound undergoes epoxide ring opening. Perchloric acid protonates the oxygen atom of the epoxide.
