Concept:
The National Education Policy (NEP) 2020 is one of the most significant educational reforms introduced in India. It replaced the National Policy on Education of 1986 and aimed to transform the entire education system from school education to higher education.
Step 1: Understand what NEP 2020 is.
NEP 2020 was designed to bring major changes in:
• School education structure.
• Higher education reforms.
• Multidisciplinary learning.
• Vocational education.
• Foundational literacy and numeracy.
• Technology integration in education.
Step 2: Identify the date of approval.
The Union Cabinet of India approved the National Education Policy on 29 July 2020.
This date is considered the official implementation and announcement date of NEP 2020.
Step 3: Analyze the options.
01 January 2021 is not the official implementation date.
29 July 2020 is the date on which the policy was approved and brought into effect.
15 August 2021 has no direct connection with the launch of NEP 2020.
01 April 2020 was before the policy was officially approved.
Step 4: Conclusion.
The National Education Policy came into effect on 29 July 2020.
Hence, option (B) is correct.
