The correct answer is: D. Peaceful Coexistence
The South Asian Association for Regional Cooperation (SAARC) is an intergovernmental organization of eight countries in South Asia: Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, Sri Lanka, and Afghanistan. It was established on 8 December 1985 in Dhaka, Bangladesh. The main aim of SAARC is to promote the welfare of the peoples of South Asia and to improve their quality of life. It does this by promoting economic growth, social progress, and cultural development in the region. SAARC also works to promote peace and security in South Asia.
Option A, Regional Cooperation, is a correct statement about SAARC, but it is not the main aim of SAARC. SAARC does promote regional cooperation, but this is not its primary goal. The main goal of SAARC is to promote peaceful coexistence in South Asia.
Option B, Internal affairs, is not a correct statement about SAARC. SAARC does not interfere in the internal affairs of its member states.
Option C, Non-alignity, is not a correct statement about SAARC. SAARC is not a non-aligned organization.
Therefore, the correct answer is: D. Peaceful Coexistence
