According to Sheldon's constitutional theory, the most likely group to become involved with crime is mesomorphs (option c). Sheldon proposed that individuals with a mesomorphic body type, characterized by a muscular and athletic build, were more likely to engage in criminal behavior. This theory suggests a link between physical characteristics and criminal tendencies.
