The correct answer is - B. It is a possessive pronoun that takes the place of a noun.
Let's go through all of these options first.
A - there are no prepositions in this sentence, so 'yours' cannot be the object of a preposition.
C - the subject of this sentence is the pronoun 'I' because it is the doer of the action
D - it is not a personal pronoun; personal pronouns are I, you, he/she/it, we, you, and they.
Therefore, the correct answer is only B - it is a possessive pronoun because it shows that the pronoun 'you' is the owner of the skateboard that the subject likes more.
I think the sentence that best supports this is "I will advise you and direct you. I should not be a man if this womanly helplessness did not just give you a double attractiveness in my eyes."
