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