The National Education Policy 2020 treats reading, writing and basic arithmetic as the foundation of all later schooling, and it declares that attaining universal foundational literacy and numeracy by 2026–27 is the highest priority of the school education system.

To deliver that goal the policy announced a dedicated national mission, set up by the Ministry of Education, with the words foundational literacy and numeracy in its own title. States were asked to prepare implementation plans under it, and the scheme NIPUN Bharat was launched in 2021 to carry it forward for children up to Grade 3.

Early childhood care and education is a separate chapter of the same policy and is served by the existing anganwadi and preschool structure, while teacher preparation is addressed through the integrated teacher education programme. A general mission on education is not the name of any body created by the policy, so it does not answer the question asked.

National Mission on Foundational Literacy and Numeracy option is correct.
