Both statements are incorrect.
Incorrect Options
Statement 1: The Constitution of India does not mandate that all Cabinet Ministers shall compulsorily be sitting members of Lok Sabha only. Article 75(5) stipulates that a minister who is not a member of Parliament for any period of six consecutive months shall cease to be a minister. This implies that a person can be appointed a minister even if they are not a member of either House of Parliament, but must become a member of either Lok Sabha or Rajya Sabha within six months. Therefore, members of the Rajya Sabha are also eligible to be appointed as Cabinet Ministers.
Statement 2: The Union Cabinet Secretariat operates under the direct charge of the Prime Minister, not the Ministry of Parliamentary Affairs. Its primary role is to provide secretarial assistance to the Cabinet and Cabinet Committees, and to ensure coordination among various ministries and departments of the Government of India.
