A good night's sleep is most likely to improve exam grades by supporting the process of priming memory consolidation. Correct option(d)
Memory consolidation is defined as a time-dependent process that converts recently learned experiences into long-term memory, presumably through structural and chemical changes in the nervous system (e.g., the strengthening of synaptic connections between neurons).
The final consolidation is the result of two major processes. These are synaptic consolidation, which occurs within hours of learning and encoding, and system consolidation, in which hippocampal memories become independent of hippocampus storage after a certain period of time.
