When Hypnotized People Are Told That They Will Fail to See

When hypnotized people are told that they will fail to see or hear something, what (if anything) changes in their perception?

A) Their visual and auditory receptors become unresponsive with a metabolism of almost zero.
B) They deny seeing or hearing the stimulus, but it alters their behavior anyway.
C) They still claim they see or hear the stimulus, but it no longer affects their behavior in any measurable way.
D) They still report seeing or hearing the stimulus, and they respond to it the same as before hypnosis.
