The Wagner-Meerwein rearrangement is a specific type of rearrangement where a carbon skeleton migrates. Among the provided options, the reaction of 3,3-Dimethyl-1-butanol to 2,3-dimethylbutane using H2SO4 is the one that involves a Wagner-Meerwein rearrangement, as it involves the formation of a carbocation and subsequent rearrangement to form a more stable product."}
