In the Traditional Information-Processing Model, One Difference Between Short-Term Memory

In the traditional information-processing model, one difference between short-term memory and long-term memory is that

A) you forget many short-term memories almost as soon as your attention is distracted; long-term memories can be available at any time.
B) your short-term memories pertain mostly to meanings, while your long-term memories pertain mostly to sounds.
C) you can store an almost unlimited amount of information in short-term memory but your long-term memory has a limited capacity.
D) you need reminders or retrieval cues to find information stored in short-term memory; you need no such help for long-term memory.
