Article 60 VCLT addresses TERMINATION OR SUSPENSION of treaty operation as a CONSEQUENCE OF BREACH. A MATERIAL BREACH of a bilateral treaty entitles the other party to:

1. Article 60(1) VCLT: 'A material breach of a bilateral treaty by one of the parties entitles the other to invoke the breach as a ground for terminating the treaty or suspending its operation in whole or in part.' 2. Article 60(3) defines 'material breach' as: (a) a repudiation of the treaty not sanctioned by the present Convention; or (b) the violation of a provision essential to the accomplishment of the object or purpose of the treaty. 3. Article 60(2) addresses multilateral treaties — more complex consultative process required. 4. Article 60(5) exempts treaty provisions relating to the protection of the human person, particularly those prohibiting reprisals against persons protected by such treaties. 5. Hence option B is correct. _Source: UN Charter 1945 / Vienna Convention on Law of Treaties 1969 / ICJ Statute / ARSIWA 2001 — Vienna Convention on the Law of Treaties 1969, Article 60_
