When a Ballerina Pirouettes, Images of the Room Move Rapidly

When a ballerina pirouettes, images of the room move rapidly across her retina. She does not perceive the room as moving while she is spinning because:

A) she has learned to disregard the retinal motion
B) she is moving too rapidly for the brain to register the changing images
C) the circular movement keeps the firing rates of all motion detectors even
D) her brain adjusts perceived movement for actual head movement
