Rods are light sensitive cells of the retina that provide information about color to the brain.
a. true
b. false

The correct answer will be option-false.

Explanation:

The eye contains a layer of photoreceptor cells at the back of the eye called retina. The retina contains two types of photoreceptor cells called  Cones and rods.

The rod cells contain only one types of pigment and are very sensitive to light and dark changes but cones contains three types of photoreceptors which are sensitive to red, blue and green color.

The cone cell sends signals to the brain about these colors where the brain perceives and produce an image.

Thus, option- false is the correct answer.
