Which of the following is a symptom of Vitamin A deficiency?

Vitamin A deficiency is characterized by several symptoms, with night blindness being one of the most prominent. This condition arises because Vitamin A is crucial for the synthesis of rhodopsin, a photopigment found in the retina that is essential for low-light vision. When there is insufficient Vitamin A, the ability to see in dim light diminishes, leading to night blindness.

Rickets is related to a deficiency of Vitamin D, calcium, or phosphate and primarily affects bone health in children. Scurvy is caused by a deficiency in Vitamin C, leading to issues such as poor wound healing and gum disease. Pellagra is associated with a deficiency in niacin (Vitamin B3), resulting in a syndrome with symptoms that include dermatitis, diarrhea, and dementia. Each of these conditions is linked to specific nutrient deficiencies unrelated to Vitamin A, making night blindness the clear indication of Vitamin A deficiency.
