The correct answer is B. Communication.
Communication is the intentional exchange of information brought about by production and perception. It is a process that involves the use of symbols, signs, or signals to convey meaning. Communication can take place through a variety of channels, including speech, writing, gestures, facial expressions, and body language.
Hearing is the process of perceiving sound waves. It is a passive process that does not require any intentional effort on the part of the listener. Speech is the production of sounds that are used to communicate. It is an active process that requires the speaker to use their vocal cords and other muscles to produce sounds.
None of the other options are correct because they do not involve the intentional exchange of information.
