Final Answer : C, Explanation :  The scenario in the question suggests that Nathan is in a dark room, which means that the light level is low. In such low light conditions, the rods in the eye become active and start functioning while the cones become inactive. Rods are responsible for night vision and are not sensitive to color. Therefore, Nathan is primarily relying on the rods in his eyes, which are responsible for night vision and not sensitive to color.
