Efren is not thinking about his girlfriend at this very moment. however, someone asks him to describe her, and without much thought, he describes her eyes, hair, and smile. thus, according to freud's three levels of consciousness, this information about his girlfriend is likely to be stored in the layer of efren's consciousness.

1) unconscious
2) preconscious
3) conscious
4) subconscious

2) preconscious

Explanation:

Sigmund Freud has given the theory of psychoanalysis and he has mention three different levels of consciousness i.e, unconscious, subconscious, and preconscious.

Preconscious: According to Freud, the preconscious level is the area or part of the consciousness that lies between the unconscious and conscious awareness. The thoughts that are being present in the preconscious level of an individual's mind are neither present in the conscious awareness and nor are buried to the unconscious level but are present somewhere in between and hence can be brought or retrieved to the consciousness.

In the question above, the information about Efren's girlfriend is likely to be present in the preconscious layer of Efren's consciousness.
