The Architects Act 1972 exists mainly to protect the title "Architect" and to regulate who can practice under it in India. That single purpose splits into two practical duties for the Council of Architecture (CoA): control entry into the profession, and control behaviour once inside it. Use that lens on each option.
- Maintaining minimum standards of architectural education: before anyone can register as an architect, the CoA has to be satisfied their degree meets a minimum bar, so it recognizes and inspects architecture schools and fixes the minimum syllabus. This is entry control, and it is a genuine CoA duty.
- Maintaining standards for professional conduct of registered architects: once registered, an architect is bound by the Architects (Professional Conduct) Regulations framed by the CoA, and the CoA can discipline an architect who breaks them. This is behaviour control, and it is also a genuine CoA duty.
- Maintaining minimum standards for master plan preparation: a master plan (or development plan) is a planning document prepared and approved under town and country planning acts, administered by planning authorities, not by the architects' regulatory body. This is outside the CoA's remit.
- Regulating building material standards for construction projects: material standards (grades of cement, steel, brick, and so on) are published as IS codes by the Bureau of Indian Standards. The CoA has no statutory role in setting these standards.
Only the first two options fall inside the CoA's actual mandate under the Architects Act 1972; the last two belong to other bodies entirely.
Let's summarize:
- CoA's job: fix minimum education standards for registration, and enforce professional conduct rules for registered architects.
- Not CoA's job: master plan standards (planning authorities) and building material standards (Bureau of Indian Standards).
The correct responsibilities are options (A) and (B).
