When Grace Falle Entered the Dark Theater,she Tripped Over Someone's

When Grace Falle entered the dark theater,she tripped over someone's foot,and spilled her popcorn.It was several minutes before she could see very well in the darkened theater.However,on the way out she noted that her eyes became accustomed to the light in only a few seconds.The most likely explanation for this would be that

A) her rod cells adapted to light faster than her cone cells did to the dark.
B) it takes longer to return rhodopsin to its original shape than it does to break it apart.
C) cone cells are more common in her retina than rod cells.
D) her fovea centralis may have been covered up by her optic disk.
E) she was probably red-green colorblind.
