B) Iodine
C) Zinc
D) Vitamin A

Answer 1

The answer is letter D.

Step-by-step explanation:

The deficiency of Vitamin A can cause these symptoms. The lack of Vitamin A in blood and tissues can cause Nyctalopia. Xerophtalmia, keratomalacia, and complete blindness can also occur since Vitamin A has a major role in phototransduction.
