Hi, the correct option would be the third option - "the keys on the kitchen counter are mine". In all other examples "on the kitchen counter" has an adverbial meaning, and the third example is the only one where this phrase is used as an adjective.
I think 1 is either A or D & 2 is either A or B. I hope I helped & I'm sorry if I'm wrong :)
The correct answer should be
⭕ C. Because I said so all hope is lost
