Hi,
In the first sentence, the subject is ‘you’.
In the second one it is ‘I’.
In the third one it is ‘You’.
To find the subject in a sentence you should look at the verb and find the person/people/thing that make the action the verb describes.
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know.
B. is the correct answer because, Russian is the name of a place or language and it needs to be capitalized. Also because the words: border, near, and the, don't need to be capitalized because they are not the name of something. Only Russian needs to be capitlaized. So it's B.
Hope I helped!
