Section 84 of the Copyright Act 1957 deals with PROTECTION OF SEPARATE RIGHTS. Where copyright is owned by joint authors (e.g. lyricist + composer), each can:

1. Section 14 Copyright Act 1957 confers different exclusive rights bundled per category of work. Section 13(4) allows separate copyright in components (lyrics is literary, music is musical, sound recording is separate). 2. Section 19(4) provides that copyright assignment may be in respect of all or any of the rights and may be applied for separate countries. 3. The 2012 Amendment inserted provisos to Section 17 ensuring that authors of underlying works retain their rights when works are incorporated in cinematograph films. 4. The Supreme Court in IPRS v. Sanjay Dalia (2015) held that lyricists and composers continue to enjoy rights in respect of their underlying works. 5. Hence each author can exercise his SEPARATE rights INDEPENDENTLY for those rights distinct from joint exercise. 6. Hence option B is correct. _Source: Patents Act 1970 / Copyright Act 1957 / Trade Marks Act 1999 (Bare Acts, IPIndia portal + Copyright Office) — Copyright Act 1957, Section 19A, Section 19; IPRS v.
