It would be A because B could be answered best with a poll graph, C with a pie graph, and D with a bar graph. Line graphs typically show speed and rate so A makes the most sense, but you are still able to do the other questions on a line graph.
Answer:
Hippocampus.
Explanation:
There are two parts of the limbic system. They are the frontal part which is the amygdala and the posterior part which is the hippocampus.
The hippocampus is an extension of the temporal part of the cerebral cortex which is a plastic-like structure that can be easily damaged by stimuli. It is packed with densed neurons and forms an S-shape at the extension of the temporal part.
It is responsible for learning and memory and damage to it can result to memory loss of recently learnt information.
