Answer» Correct option is (C) vitamin A For explanation I would SAY: Vitamin A deficiency (VAD) or HYPOVITAMINOSIS A is a lack of vitamin A in BLOOD and tissues. It is common in poorer countries but RARELY seen in more developed countries. Nyctalopia (night blindness) is one of the first signs of VAD.
