I think that it would be A- direct your research, but since I do not know the context of you question.
A. The evidence is relevant because it shows that people interacting through technology are often rude.
The correct answer is reflexive.
Reflexive pronouns are used when the object of the sentence is the same person as the subject. Here, the subject is Johnny and given that he bought something for himself, he is also the object. Although the pronoun himself can sometimes be intensive, this is not the case where it is. Intensive pronoun would be if the sentence said: Johnny himself bought a new basketball.
Second person is when something is written with the words "You" and "Your."
For example, "You gazed out the window."
