Final answer:
Craik and Lockhart's levels of processing are shallow, intermediate, and deep (C: Shallow, Intermediate, and Deep), which pertain to the depth of cognitive processing involved in memory retention.
Step-by-step explanation:
According to Craik and Lockhart (1972), the three levels of processing are shallow, intermediate, and deep. Thus, the correct answer would be C: Shallow, Intermediate, and Deep. These levels describe the framework for memory processing: shallow processing might involve simple, surface-level attention to physical features of a stimulus, intermediate processing could involve a bit more depth such as recognizing patterns or words, while deep processing involves an in-depth understanding such as the meaning behind information or its implications, which is most likely to lead to better retention of information.
