B. Phosphorus
C. Sulphur
D. Magnesium

Answer 1

Hint: Biotin is a water-soluble vitamin that is part of the B family of vitamins. It is also known as vitamin H. Your body requires biotin to help turn those nutrients to energy. It also plays a crucial role in the wellbeing of your hair, skin , and nails.

Complete Answer:
- Biotin is an important component of enzymes involved in the metabolism of fats and carbohydrates, affecting cell growth and affecting amino acids involved in protein synthesis. Biotin aids in various metabolic processes involving the movement of carbon dioxide. It may also be beneficial to maintain a stable blood sugar level.
- Normal biotin blood plasma levels in healthy individuals range from 200 to 1200 ng / L, with an optimal level of 400-500 ng / L in younger adults and children.
- Depending on the cause, biotin deficiency is often present when the plasma biotin level is below 100 ng / L.
- There are a variety of unusual metabolic disorders in which the individual's metabolism of biotin is irregular, such as deficiency in the holocarboxylase synthetase enzyme, which covalently binds biotin to carboxylase, where biotin is the cofactor.
- Sulfur is a non-metallic factor found in all proteins; a mineral-a constituent of vitamin B1 (thiamine) and biotin and several important amino acids required for the development of collagen (which helps to shape bones, tendons, and connective tissues) and a constituent of keratin (hair, skin , and nails); commonly occurring in nature both free and mixed in several allotropic forms.

Thus the correct Answer is Option(C) Sulphur.

Note: In humans, biotin absorption occurs in the small intestine. Other essential sites that play a role in normal biotin physiology include the liver (primary biotin utilisation location), the kidney (filtered biotin reabsorption location) and the placenta (biotin transfer site from the maternal circulation to the embryo).
