The correct statement that is not correct would be B) Cable TV, E-mail, Internet are not forms of mass media.
 This statement is incorrect because Cable TV, E-mail, and the Internet are indeed forms of mass media. They have the ability to reach a large audience and disseminate information widely. Cable TV provides television programming to a wide range of viewers, while E-mail and the Internet allow for the distribution of information to a mass audience through electronic means.
