According to the optimal spacing theory, the best retention of studied material occurs when study sessions are spaced further apart in time and followed by a longer interval before testing. Choice C has two study periods spaced 2 days apart from each other, followed by a test 10 days later, which fits this pattern. Choices A, B, and D have study sessions spaced too closely together or testing intervals that are too short.
