The Lok Sabha Secretariat operates under the direct supervision of the Speaker of Lok Sabha. The Lok Sabha Secretariat is responsible for providing administrative and procedural support to the Lok Sabha, which is the lower house of the Indian Parliament.
Option 1: The Cabinet Secretary does not have direct supervision over the Lok Sabha Secretariat. The Cabinet Secretary is the highest-ranking civil servant in the Government of India and is responsible for coordinating the activities of various government ministries.
Option 2: The Minister of Parliamentary Affairs is not directly involved in the supervision of the Lok Sabha Secretariat. The Minister of Parliamentary Affairs is responsible for coordinating the functioning of the government in the Parliament and acts as a link between the government and the Parliament.
Option 4: The Prime Minister of India is not directly responsible for the supervision of the Lok Sabha Secretariat. The Prime Minister is the head of the government and is responsible for the overall functioning of the government, but the day-to-day administration of the Lok Sabha Secretariat is not under the direct supervision of the Prime Minister.
Therefore, option 3 is the correct answer as the Speaker of Lok Sabha directly supervises the Lok Sabha Secretariat.
