Answer:

B. The availability of social media led to a change in who participated in the political conversation

Explanation:

With social media, anyone's voice can be exposed. There's always a chance of being heard and, to an extend, there's a way for you to debate with anyone and contest anyone's word, no matter how famous or popular they are. With social media, the debate includes society much more than it has every been included.
