Regarding the use of hypnosis to assist memory, what is the main problem observed in the recall of information in studies so far?

The main problem observed in the recall of information is: People under hypnosis are vulnerable to prompts and suggestion and can create a false memory.

When people under the influence of hypnosis, they can't differentiate between illusion and the actual event.

If a memory is added during hypnotized state, that person could perceive it as an illusion and create a false memory.
