  • Vitamin D :
    • Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and many other biological effects. 
    • Found in fortified milk and other dairy products.
  • Hence, option 3 is incorrectly matched.

  • The vitamins are natural and essential nutrients, required in small quantities, and play a major role in growth and development, repair, and healing wounds.
  • Types of Vitamins -
    • Fat-Soluble Vitamins:
      • Fat-soluble vitamins are stored in the fat cells and as the name suggests, these vitamins require fat in order to be absorbed.
      • Vitamin A, D, E, and K are fat-soluble vitamins.
    • Water-Soluble Vitamins:
      • Water-soluble vitamins are not stored in our body as its excess gets excrete through the urine.
      • Therefore, these vitamins need to be replenished constantly.
      • Vitamin B and C are water-soluble vitamins.
  • Vitamin B12:
    • Vitamin B12, also known as cobalamin, is a water-soluble vitamin involved in the metabolism of every cell of the human body.
    • It is a cofactor in DNA synthesis and in both fatty acid and amino acid metabolism.
    • Found in fish, poultry, meat and dairy products.
  • Vitamin C:
    • Vitamin C is an essential nutrient involved in the repair of tissue and the enzymatic production of certain neurotransmitters. 
    • Found in citrus fruits and juices, such as oranges and grapefruits.
  • Vitamin K :
    • Vitamin K refers to structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements.
    • The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation or for controlling binding of calcium in bones and other tissues. 
    • Found in dark green leafy vegetables and in turnip or beet green.
