Answer

improve banking sector's ability to deal with economic stress and improve risk management

(a) Incorrect. This refers to the Convention on Biological Diversity (CBD), which deals with biodiversity conservation and sustainable use, not Basel III.
(b) Correct. Basel III is an international banking regulatory framework issued by the Basel Committee on Banking Supervision to strengthen banks’ capital, liquidity, and risk management so they can better withstand financial stress.
(c) Incorrect. This describes climate agreements like the Kyoto Protocol, which imposed heavier emission-reduction obligations on developed countries.
(d) Incorrect. This relates to the Montreal Protocol, which supported technology transfer to help developing countries phase out CFCs.

Therefore, the correct answer is (b).
