Step 1: Concept
The Pharmacy Council of India (PCI) is the statutory body regulating pharmacy education and profession in India.
Step 2: Meaning
Its powers are focused on setting educational standards and maintaining a register of qualified professionals.
Step 3: Analysis
Regulating standards, prescribing education for registration, and maintaining the central register are all core PCI functions. However, pharmacists in India do not have the legal authority to prescribe drugs; that is the role of Registered Medical Practitioners.
Step 4: Conclusion
Since prescribing is not a legal role for pharmacists in India, the PCI does not have a function to "allow" it.
Final Answer: (D)
