What is the function of NIRF?

The correct option is: Providing a framework for ranking of higher educational

Explanation:
NIRF stands for the National Institutional Ranking Framework. It is a methodology adopted by the Ministry of Education (formerly known as the Ministry of Human Resource Development), Government of India, to rank institutions of higher education in India.
Launched in September 2015, the framework outlines a broad set of parameters to evaluate and rank universities, colleges, and other higher educational institutes across the country. These parameters include:
1. Teaching, Learning, and Resources
2. Research and Professional Practice
3. Graduation Outcomes
4. Outreach and Inclusivity
5. Perception

While other bodies like the University Grants Commission (UGC) are responsible for providing grants, and universities themselves or respective councils design the curriculum, the sole function of NIRF is to provide a reliable framework for ranking higher educational institutions.
