The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Biotin is a water-soluble B-complex vitamin that plays a vital role as a coenzyme in carboxylase-catalyzed metabolic reactions.
Many B-complex vitamins have historical alternative letter designations based on early discovery or physiological roles.
Step 2: Detailed Explanation:
Let us review the historical designations of these vitamins:
- Biotin (Vitamin B7): Historically designated as Vitamin H.
The letter 'H' stands for 'Haar und Haut' (German for 'hair and skin'), reflecting its essential role in maintaining healthy skin, hair, and nails.
A deficiency in biotin can cause hair loss (alopecia) and skin inflammation (dermatitis).
- Vitamin G: An old, obsolete designation for Riboflavin (Vitamin B2).
- Vitamin L: An obsolete term used for certain factors thought to promote lactation.
- Vitamin K: A separate, fat-soluble vitamin essential for blood coagulation (where 'K' stands for 'Koagulation' in German).
Therefore, Biotin is designated as Vitamin H.
Step 3: Final Answer:
Biotin is often denoted as Vitamin H, which corresponds to Option (B).
