The answer is letter A.
Memory is responsible for storing and retrieving
information from our cognitive system. Our memories are comprised of all the
series of skills and learning we have earned through the beginning. Memories
are an integral part of the brain that makes us remember certain sensations and
associate them with the proper response. A lot of the activity that goes on in
our external environment is a result of all the details and thoughts that we
have in our brains. Without memory, we will be like other organisms who only
act out by instincts.
