1. The correct answer is A. Rick. Since pronouns are basically words that refer to other words by replacing them, the pronoun "your" here refers back to the person who has been named as Rick at the beginning of the sentence. The word that is being referred to is called antecedent. Usually, it is placed before the pronoun.
2. The correct answer is A. Jorge. Again, we have the pronoun "he" referring back to its antecedent "Jorge." It is part of the language economy or efficiency; we don't need to say "Jorge asked if Jorge could sit in our spare seat at the concert." We can say it in a more elegant and efficient way by replacing the second "Jorge" with a personal pronoun that refers to him, and everybody will understand it.
