In Order to Detect That a Red Shape Was Moving

In order to detect that a red shape was moving, it is likely that

A) the neural system detecting motion and the neural system detecting the color red were both firing in synchrony.
B) only the neural system detecting the color red was firing, as color is visually more important than motion.
C) only the neural system detecting motion was firing, as motion is visually more important than color.
D) the neural system detecting motion and the neural system detecting the color red were both firing but at an asynchronous rate.
