• C. Vitamin-A–Fat soluble–Beri-Beri
• D. Vitamin-K–Water soluble–Pellagra

Answer 1

The correct option is A Vitamin-A–Fat soluble–Night blindness


Vitamins are categorized as fat-soluble and water-soluble. Vitamin B and C are considered as water-soluble. While, vitamins A, D, E and K are fat-soluble vitamins, which means they are soluble in fats (lipids).

The deficiency of vitamin A results in night-blindness, deficiency of vitamin K causes Bleeding disorders.

Vitamin A, also known as retinol, is a fat-soluble vitamin. Night blindness is one of the first signs of vitamin A deficiency. In its more severe forms, vitamin A deficiency contributes to blindness by making the cornea very dry, thus damaging the retina and cornea.
So, the correct option is A.
