According to the National Education Policy (NEP) 2020, the policy aims to provide exposure to vocational education to at least 50% of learners through the school and higher education system by 2025. This confirms that statement 1 is correct. Additionally, the NEP 2020 emphasizes that secondary schools should collaborate with Industrial Training Institutes (ITIs), Polytechnics, and local industries to enhance vocational education, confirming that statement 2 is also correct. However, the policy does not state that vocational education is to be exclusively provided by NGOs. Instead, it focuses on integrating vocational education into mainstream education and involves various stakeholders, including educational institutions and industries. Therefore, statement 3 is incorrect. Hence, the correct answer is option 2: 1 and 2 only.
