Final answer:
The hippocampus is essential for creating new explicit memories. The correct answer is d) hippocampus.
Step-by-step explanation:
The correct answer is d) hippocampus.
The hippocampus is essential for creating new explicit memories, which are memories that require conscious recollection of specific events or facts. Examples of explicit memories include remembering someone's name or recalling what happened on a specific day.
On the other hand, implicit memories, which are memories that are formed without conscious effort, do not rely on the hippocampus. These types of memories include skills and habits that we learn through repetition, such as riding a bike or typing on a keyboard.
