The pattern of firing of receptor activity in response to red would be _____.
A) large firing from the S receptor, medium firing from the M receptor, and little firing from the L receptor
B) large firing from the S receptor, large firing from the M receptor, and little firing from the L receptor
C) little firing from the S receptor, a moderate firing from the M receptor, and large firing from the L receptor
D) large firing from the S receptor, large firing from the M receptor, and large firing from the L receptor

Question

The pattern of firing in response to red light involves little firing from the S (short-wavelength) receptor, moderate firing from the M (medium-wavelength) receptor, and large firing from the L (long-wavelength) receptor, as red light is closer to the long-wavelength part of the spectrum.
