Consider the following statements:
1. The Sustainable Development Goals were first proposed in 1972 by a global think tank called the 'Club of Rome'.
2. The Sustainable Development Goals have to be achieved by 2030.
Which of the statements given above is/are correct?

Correct Option: (b) 2 only

The Sustainable Development Goals (SDGs) are a collection of 17 global goals designed to be a blueprint to achieve a better and more sustainable future for all by 2030, making statement 2 correct. Statement 1 is incorrect because the SDGs were adopted by the UN in 2015, succeeding the Millennium Development Goals; it was the 'Limits to Growth' report by the Club of Rome in 1972 that dealt with resource limits, not SDGs.
