The correct answer is Administrative Reforms Commission of India (1966 - 70).
The anti-corruption ombudsman (Lokayukta at State level and Lokpal at Central level) both at the centre and the states were first conceptualized by the First Administrative Reforms Commission of India headed by Morarji Desai.
The report published by FirstAdministrative Reforms Commission in 1966 recommended the creation of two independent authorities i.e. the Lokpal at the centre and the Lokayuktas in the states to look into complaints against public functionaries, including Members of Parliament as well.
