Exp) Option a is the correct answer.

Committee on Government Assurances, Committee on Subordinate Legislation, Committee on Papers Laid on the Table, Committee on Welfare of SCs and STs, Committee on Empowerment of Women and Joint Committee on Offices of Profit come under the group of parliamentary committees to scrutinise and control.

Option 1 is correct. Committee on Government Assurances examines the assurances, promises and undertakings given by ministers from time to time on the floor of the House and reports on the extent to which they have been carried through. In the Lok Sabha, it consists of 15 members and in the Rajya Sabha, it consists of 10 members. It was constituted in 1953.

Option 2 is correct. Committee on Subordinate Legislation examines and reports to the House whether the powers to make regulations, rules, sub-rules and bye-laws delegated by the Parliament or conferred by the Constitution to the Executive are being properly exercised by it. In both the Houses, the committee consists of 15 members. It was constituted in 1953.

Option 3 and 4 are incorrect. Committee of Privileges and Ethics Committee comes under parliamentary committees to inquire. The functions of Committee of Privileges are semi-judicial in nature. It examines the cases of breach of privileges of the House and its members and recommends appropriate action. The Lok Sabha committee has 15 members, while the Rajya Sabha committee has 10 members.

Ethics Committee was constituted in Rajya Sabha in 1997 and in Lok Sabha in 2000. It enforces the code of conduct of members of Parliament. It examines the cases of misconduct and recommends appropriate action. Thus, it is engaged in maintaining discipline and decorum in Parliament.
