Which of the following statements accurately distinguishes between rods and cones in the human eye?

  • A: Rods are primarily responsible for color vision, while cones are more sensitive to dim light.
  • B: Cones enable us to see at night in black and white, whereas rods provide detailed color vision in bright light.
  • C: Rods are more sensitive to light and are responsible for black-and-white vision, while cones are less sensitive but provide color vision.
  • D: Both rods and cones are equally sensitive to light and contribute equally to both color and night vision.

Explanation

The text states: 'Rods are more sensitive to light than cones are, but they do not distinguish colors; rods enable us to see at night, but only in black and white. Cones provide color vision, but, being less sensitive, contribute very little to night vision.'
