Step 1: Clarify the topographical model.
Freud divided mind into {conscious, preconscious, unconscious}. The preconscious contains material outside current awareness but easily retrievable—{available memory}.
Step 2: Resolve the terminology.
Many textbooks loosely use “subconscious” for this preconscious layer (not for id/ego structures).
Step 3: Conclude.
\[
\boxed{\text{Available memory / Preconscious (Option A).}}
\]
