- A-II, B-III, C-IV, D-I
- A-III, B-II, C-I, D-IV
- A-I, B-IV, C-III, D-II
- A-IV, B-III, C-II, D-I
The Correct Option is C
Solution and Explanation
Step 1: Iron (Fe) is a major component of proteins such as hemoglobin, and it is essential for their function. It acts as a major constituent of proteins. Hence, A-I is correct.
Step 2: Potassium (K) plays a significant role in stabilizing protein structures and enzyme activity. It helps stabilize the overall structure of proteins. Therefore, B-IV is the correct option.
Step 3: Phosphorus (P) is an important component of certain proteins like phosphoproteins and also plays a role in the synthesis of nucleic acids. Thus, C-III is correct.
Step 4: Sulfur (S) is involved in the stabilization of protein structures, especially in the form of disulfide bonds between cysteine residues. Therefore, D-II is correct.
Conclusion: Thus, the correct matching is: A-I, B-IV, C-III, D-II.
