d)yours,mine

Answer 1

these books are different. Yours has 28 pages , but mine has only 25.

Answer 2

The correct answer is, “yours, mine.”

When it comes to using these pronouns then it can be extremely confusing.

This type of pronouns must be cleared off in terms of yours and mine.

The ‘yours’ is used in terms of another person thing whereas ‘mine’ is used with the speakers' possession that can be anything.  

This mainly talks about things and possession only.
