The debates on 'Common but differentiated responsibilities' at the Rio Earth Summit in 1992 are-

(A) The industrialised countries are mainly responsible for the environmental crises and must take more responsibility for undoing the damage.
(B) Environmental restrictions must be applied to all countries equally.
(C) Developing countries should be entirely exempt from restrictions related to environmental protection.
(D) All the countries of the world are equally responsible for the current environmental crises.

Choose the correct answer from the options given below:

(A) and (D) only

The correct answer is Option (1) → (A) and (D) only

The question specifically asks about the debates at the Rio Earth Summit, where two contrasting views were presented:

• (A) is correct because developing countries argued that industrialised nations are mainly responsible for environmental degradation and should take greater responsibility.
• (D) is also correct because developed countries argued that all nations should be equally responsible for addressing environmental problems.

(B) is incorrect because the debate did not specifically argue for identical restrictions across all countries.
(C) is incorrect because no group supported complete exemption of developing countries; responsibility was accepted as shared but differentiated.
