Use the elimination process.
Well, if the teachers in his school are republican, does it mean he is? Nope.
If his parents are republicans, does it mean he is? Most likely.
Just because he sees them on T.V., does it mean he is one? Nope.
His state governor is a republican. But that doesn't mean he is one, right? Nope. He may be a democratic.
So, #2 is the answer.
his parents are probably republicans
The most likely reason for John to identify as a Republican is that his parents are probably Republicans, as children's political beliefs are often influenced by their family's views. While teachers, media, and political leaders can have some impact, family is typically the strongest influence. Thus, option B is the best choice.
