I believe the best example of manipulating an audience through media is letter B.

The answer is below
Explanation:
Given that the ideal image of a successful person presented on the internet can be provided by anybody without proper assessment or regulation.
Therefore, the ideal image of a successful person presented can be a person of a questionable character such as gamblers, corrupt politicians, adult actors, and many more.
Hence, such a controversial successful person can influence teenagers negatively, thereby harmful to their development.
Language is a system of signs represrnting ideas to convey a message. Those symbols, which are words can be arbitrary, ambiguous, abstract representations of other phenomena. Words are not intrinsically connected to what they represent. Meanings of words can shift over time. The arbitrary character allows us to invent new words.
Language is ruled guided, simply put, verbal communication is guided by unspoken but broadly understood rules.
So I would say that option A, C and D are correct.
Meanwhile, I think that option B is incorrect since a mean of communication is understood as the tool and technology employed in order to convey a message, exchange information, ideas.
In 1848, one day a man named James Wilson Marshal was digging until he found something shining, gold! Marshal wasn't even looking for gold. In fact, he was preparing to build a sawmill near a river until he found his new shocking discovery. When the word got out that he found some gold, people headed west hoping to find some gold and get rich. (I only did the top paragraph, do you need the second?)
