Which one of the following is the correct matching of a vitamin, its n...
A vitamin is an organic molecule (or a set of molecules closely related chemically, i.e. vitamers) that is an essential micronutrient which an organism needs in small quantities for the proper functioning of its metabolism. Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet. Vitamin C can be synthesized by some species but not by others; it is not a vitamin in the first instance but is in the second. The term vitamin does not include the three other groups of essential nutrients: minerals, essential fatty acids, and essential amino acids. Most vitamins are not single molecules, but groups of related molecules called vitamers. For example, there are eight vitamers of vitamin E: four tocopherols and four tocotrienols. Some sources list fourteen vitamins, by including choline, but major health organizations list thirteen: vitamin A (as all-trans-retinol, all-trans-retinyl-esters, as well as all-trans-beta-carotene and other provitamin A carotenoids), vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B7 (biotin), vitamin B9 (folic acid or folate), vitamin B12 (cobalamins), vitamin C (ascorbic acid), vitamin D (calciferols), vitamin E (tocopherols and tocotrienols), and vitamin K (phylloquinone and menaquinones)
Vitamin A - Fat soluble- Night blindness
Vitamin B1- water soluble- beri beri , wernicke korsakoff syndrome.
Vitamin B2- water soluble - Ariboflavinosis
vitamin B3- water soluble- pellagra
Vitamin B5- water soluble- paresthesia
vitamin B6 - water soluble- anemia
vitamin B7- water soluble- dermatitis

Both vitamin A and K are fat soluble vitamins. Deficiency of vitamin A leads to night blindness as the retinal which serves to send the nerve impulses from retina to brain is a derivative of vitamin A. Deficiency of vitamin K cause inability of blood clotting. So, option d is correct.
