Answer : 1. "Vitamins B & C"
Explanation :

Answer: A) Vitamins B & C Explanation: Vitamins are essential nutrients found in foods. They perform specific and vital functions in a variety of body systems, and are crucial for maintaining optimal health.   The two different types of vitamins are fat-soluble vitamins and water-soluble vitamins.   Fat-soluble vitamins :  Vitamins A, D, E and K — dissolve in fat before they are absorbed in the bloodstream to carry out their functions. Excesses of these vitamins are stored in the liver, and are not needed every day in the diet.   Water-soluble vitamins : Vitamins dissolve in water and are not stored by the body. Since they are eliminated in urine, we require a continuous daily supply in our diet. The water-soluble vitamins include the vitamin B-complex group and vitamin C.   Water-soluble vitamins are easily destroyed or washed out during food storage or preparation.
