The number of naturally accusing chemical elements involved in bio chemical reaction is
Correct answer: C. 92
- A. 126
- B. 86
- C. 92
- D. 206
Explanation
There are 92 naturally occurring chemical elements traditionally recognised in the periodic table, although only a smaller subset is essential for living organisms. Students may choose 126 by confusing naturally occurring elements with the total number of known or predicted elements, but 92 is the standard count of naturally occurring elements.

About Classification of Biological Molecules
Biological molecules are classified as carbohydrates, lipids, proteins and nucleic acids, with water, minerals and vitamins also supporting cellular processes. The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
