Explanation:
Detailed explanation-1: -Statement 1: Cone cells are sensitive to dim light.
Detailed explanation-2: -These specialized cells are called photoreceptors. Which are: rods and cones. Cones are more sensitive to bright light. Rods are most sensitive to dim light.
Detailed explanation-3: -Rod cells are able to function in dim light but do not perceive colour. Rod cells are able to work in low light intensity because the cell can respond to a single photon of light (more sensitive). The brain requires fewer than 10 such responses to perceive the sensation of a flash of light.
