Cone cells in human eye are responsible for color vision. The cone cells are of three types: Red (R), Green (G) and Blue (B) cells. Each type of cone cell responds to a range of wavelengths, with a particular wavelength showing the maximum response. Given below is a graph showing relative response of rods and cone cells in different wavelengths of light.
Which of the cone cell(s) will respond to wavelengths in the orange region?
(a) Blue and red
(b) Red and green
(c) Blue and green
(d) only red
