Correct Answer - Option 4 : X-vitamin C, Y-iron, Z-citrus fruits

Explanation:

  • Vitamin A deficiency can lead to night blindness and poor vision.
  • B vitamins are a class of water-soluble vitamins.
  • Vitamin B refers to several different types of vitamins that, together, are known as the B-complex vitamins.
  • ​The commonly used Vitamin B Complex is constituted of 8 vitamins.
    • Thiamin (vitamin B-1)
    • Riboflavin (vitamin B-2)
    • Niacin (vitamin B-3)
    • Pantothenic acid (vitamin B-5)
    • Vitamin B-6
    • Biotin (vitamin B-7)
    • Folate (vitamin B-9)
    • Vitamin B-12
  • Deficiency of Vitamin C can cause scurvy, a disease that is characterised by bleeding gums, skin spots, and swelling in joints.
    • It also affects the immune system and can even be fatal in acute conditions.
  • Vitamin C has been shown to enhance iron absorption.
  • It captures non-heme iron and stores it in a form that's more easily absorbed by your body.
  • Foods high in vitamin C include citrus fruits, dark green leafy vegetables, bell peppers, melons and strawberries.
  • Citrus fruits are an excellent source of vitamin C. 

So from the above points, we can say that-

'X' = Vitamin C

'Y' = Iron (mineral)

'Z' =  (Food) Citrus fruits
