Which one of the following commissions was not associated with public services in India?

The Aitchison Commission (1886) was established to reorganize the civil services into Imperial, Provincial, and Subordinate categories [2]. The Islington Commission (1912) was a Royal Commission on Public Services that recommended increasing Indian representation in higher posts [1][2]. The Lee Commission (1923) focused on the Superior Civil Services and recommended the immediate establishment of a Public Service Commission, which led to its creation in 1926 [2]. In contrast, the Radhakrishnan Commission (1948-1949), also known as the University Education Commission, was appointed by the Government of India to report on Indian university education and suggest improvements to suit the needs of the newly independent nation. It was not associated with the reform or administration of public services. Therefore, the Radhakrishnan Commission is the correct answer as it pertains to the education sector rather than the civil services.
