The TRIPS Agreement (Annex 1C to the WTO Agreement, 1994) sets MINIMUM STANDARDS for IP protection in Member countries. The minimum term for COPYRIGHT under TRIPS Article 12 is:

1. TRIPS Article 12 (Term of Protection): 'Whenever the term of protection of a work, other than a photographic work or a work of applied art, is calculated on a basis other than the life of a natural person, such term shall be no less than 50 years from the end of the calendar year of authorized publication, or, failing such authorized publication within 50 years from the making of the work, 50 years from the end of the calendar year of making.' 2. TRIPS incorporates Berne Convention Article 7 — which fixes the minimum as the life of the author + 50 years for natural-person works. 3. India's Copyright Act 1957 grants a longer term: life + 60 years (Section 22). 4. Hence option B is correct. _Source: Patents Act 1970 / Copyright Act 1957 / Trade Marks Act 1999 (Bare Acts, IPIndia portal + Copyright Office) — TRIPS Agreement 1994, Article 12 read with Berne Convention Article 7_
