Match the following terms in relation to then corresponding sources:

List – I		List – II
(a)	Macro-mineral	(i)	Copper
(b)	Macro-nutrient	(ii)	Calcium
(c)	Micro mineral	(iii)	Folic acid
(d)	Micro nutrient	(iv)	Fatty acid

Choose the correct options from the codes given below:

The correct option is 'a - ii, b - iv, c - i, d - iii'​.

Key Points

• Macro-mineral (a) is associated with Calcium (ii).
  • Macro-minerals are those minerals that are required by the body in relatively large amounts. Calcium is one of the essential macro-minerals needed for bone health and various body functions.
• Macro-nutrient (b) is associated with Fatty acid (iv).
  • Macronutrients are nutrients that the body needs in large amounts and include carbohydrates, proteins, and fats. Fatty acids are a key component of fats, which are a type of macronutrient.
• Micro mineral (c) is associated with Copper (i).
  • Microminerals, also known as trace minerals, are required by the body in small amounts. Copper is an essential trace mineral necessary for various bodily functions, including iron metabolism.
• Micro nutrient (d) is associated with Folic acid (iii).
  • Micronutrients are required in small quantities and include vitamins and minerals. Folic acid, a type of B vitamin, is an essential micronutrient crucial for DNA synthesis and cellular growth.

Additional Information

• Calcium: Essential for bone and teeth formation, muscle function, and nerve signaling.
• Fatty Acids: Important for energy storage, cell membrane structure, and hormone production.
• Copper: Involved in red blood cell formation, immune function, and the maintenance of nerve cells and the immune system.
• Folic Acid: Vital for proper brain function and plays an important role in mental and emotional health. It is especially important during periods of rapid growth such as pregnancy and fetal development.
