Rats can perform the delayed nonmatching-to-sample task almost as well as monkeys at retention delays of up to a minute or so. This means that they perform at levels significantly above chance. Option A, B, and C are incorrect as they suggest chance level or only slightly above chance level performance. Option E is also incorrect as it suggests that rats can perform as well as humans at retention delays of up to 10 minutes, which is not the case.
