Final answer:
The temporal lobe contains most of our long-term memories and is responsible for memory formation. Therefore, the correct option is 1.
Step-by-step explanation:
One area of the brain known as the temporal lobe is responsible for processing auditory data as well as creating and storing memories. The hippocampus, one of its constituent parts, is essential for the consolidation of declarative memories, or memories pertaining to facts and events.
Complex neural networks located throughout the temporal lobe are responsible for storing and retrieving long-term memories. While the frontal lobe is important in personality, decision-making, and executive processes, it is not the main location for long-term memory storage. The occipital lobe is principally in charge of processing visual information.
Therefore, the correct option is 1.
