"she" would be the pronoun.
You can rewrite this question as "She is your best friend?"
So in that case, "she" would be the subject.
In English, you just switch around "is" and the subject to make a question and make it sound Englishy
PS in Italian (and probably other languages) you would just say "She is your best friend?"
The answer is letter D. the object of the sentence.
Since "a frog" is the recipient of the subjects action, it is considered the object of the sentence.
Thank you for posting your question. Feel free to ask me more.
