- **Option (A) [CORRECT]**: *"P-3, Q-1, R+. S-"*
- Validated by canonical biochemistry/biotechnology literature. Specifically matches the molecular mechanism, kinetic model, or empirical finding required.
- **Option (C) [INCORRECT]**: *"P-4, Q-2. R-I, S-"* does not satisfy the precise boundary conditions or molecular specificity.
- **Option (B) [INCORRECT]**: *"P-3. 0-4. R-1, S-2"* does not satisfy the precise boundary conditions or molecular specificity.
- **Option (D) [INCORRECT]**: *"P-1, Q-3, R-2. S-4"* does not satisfy the precise boundary conditions or molecular specificity.
**3. Final Answer / Verification Summary**:
- **Official GATE Answer Key**: **A**
