There are two types of committee system in the House of parliament as part of their operations and one of such is

Analyze the question: The question asks which option is one of the committee types used in a legislature (House of Parliament) to carry out its work.

Explain the concept: Legislatures do much of their detailed work in committees. The common types are:

1. Standing committees: permanent committees (e.g., Public Accounts Committee, Appropriations Committee) that deal with specific subjects.
2. Select or ad hoc committees: set up temporarily for a specific task, and dissolved after they report.
3. Committee of the Whole House: the entire membership of the House sits as a committee, usually to consider a bill clause by clause or money matters. The Speaker steps down and a chairman presides, and the rules are less formal.
4. Joint committees: members drawn from both chambers.

The "two types" the question refers to are usually presented as standing committees and the Committee of the Whole House (or ad hoc/select committees in some textbooks).

Solution (checking each option):

• A. Parliamentary service board: This is an administrative body that manages staff and welfare matters. It is not a legislative committee type.
• B. Expert committee: This is not a recognized committee type in parliamentary procedure.
• C. Committee of the Whole House: This is a recognized committee system in which the entire House sits as a committee. ✔
• D. Leadership Committee: This is not a standard committee type in the legislature.

Answer: The correct option is C. Committee of the Whole House.

Exam tip: When you see "types of committees in a legislature," think Standing, Select/Ad hoc, Joint, and Committee of the Whole House. Any option that sounds like an administrative body (e.g., a "board") or a vague name (e.g., "expert" or "leadership") is usually a distractor.
