Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R).
Assertion (A) : India's success is critical for the global success of Sustainable Development Goals.
Reason (R) : India accounts for nearly one-sixth of the total world population.
Select the correct answer from the code given below :
Code :

Both statements are correct, and the Reason (R) provides the logical basis for the Assertion (A). India is home to approximately 1.4 billion people, representing nearly 1⁄6 (one-sixth) of the total world population. Due to this massive demographic weight, the global achievement of the Sustainable Development Goals (SDGs) is mathematically and practically dependent on India's progress.

United Nations officials and NITI Aayog have frequently emphasized that "the 2030 Agenda for Sustainable Development will succeed only if India succeeds." India's performance in critical areas such as poverty eradication (SDG 1), health (SDG 3), and clean energy (SDG 7) significantly shifts global statistical averages. For instance, India's success in providing sanitation and electricity to hundreds of millions has been a primary driver of global progress in those specific goals. Therefore, India's scale makes its success critical for global success.
