B)It states that there are three types of rods present in the human visual system.

The trichromatic theory proposed by Hermann von Helmholtz states that any color in the spectrum can be matched by combining three other wavelengths, which are red, green, and blue. This theory is also known as the Young-Helmholtz theory, and it explains how the human visual system detects and distinguishes different colors. It is different from the opponent-process theory, which states that there are four primary colors and that cells in the visual system respond to red-green and blue-yellow colors in an opponent fashion.
