According to freud, the mind contains information that you have stored in memory and are not currently aware of but can access.

 According to Freud, the preconscious mind contains information that you have stored in memory and are not currently aware of but can access. Freud believed the mind was composed of three parts: the id, ego, and superego. The preconscious mind contains thoughts that are unconscious but can be easily recalled.

The correct answer is the preconscious mind. 

The preconscious according to Freud refers to thoughts that are unconscious at a given moment, however, they are not repressed and can thus become conscious or be recalled easily. An example of the preconscious mind is your telephone number. In a given moment you might not be thinking about your telephone number, but the moment you need to jot it down on a form, it becomes available in your conscious mind.
