Tulving says that episodic memory is a uniquely human capacity. Clayton conducted experiments on animals.
So I would choose B!
As Tulving considers episodic memory a uniquely human capacity, he will agree that animals do hot share.....
Clayton also agrees with B because - "Subsequently, Clayton et al.
developed criteria to test for episodic memory in animals." - this statements means that Clayton, after acknowledging Tuvling's theory wanted to check whether it is the same in animals. So he can compare.
I hope I am right!!
