The correct answer is the limbic system, which plays a crucial role in the formation, organization, and storage of long-term memories. Within the limbic system, structures such as the hippocampus and the amygdala are particularly significant for processing memory. The hippocampus is essential for the consolidation of information from short-term memory to long-term memory, while the amygdala is involved in attaching emotional significance to memories, which can also affect how well they are remembered.

In contrast, other brain regions mentioned have different primary functions. The cerebrum is primarily associated with higher brain functions, such as thought, action, and sensory processing, but it does not specifically handle the processes crucial for forming long-term memories. The brain stem controls basic life functions such as breathing and heart rate, and does not participate in memory processing. The cerebellum is mainly responsible for motor control and coordination and does not significantly play a role in memory formation. Thus, the involvement of the limbic system is essential and specific to the processes of long-term memory retention and retrieval.
