Vedclass · Answer

(C) Night blindness,also known as nyctalopia,is a condition where an individual has difficulty seeing in low light or darkness.This condition is primarily caused by a deficiency of Vitamin $A$ (retinol).Vitamin $A$ is essential for the formation of rhodopsin,a pigment found in the rod cells of the retina that is responsible for vision in low-light conditions.Therefore,a lack of Vitamin $A$ impairs the function of rod cells,leading to night blindness.
