Explanation

Aqua regia is a mixture of concentrated hydrochloric and nitric acids that can dissolve gold and platinum. Chloroform, CHCl₃, is an organic solvent and is not the strong acid described in the reason. The assertion is true and the reason false; this does not claim chloroform can never participate in any reaction.
