The Committee on Subordinate Legislation (CSL) is specifically tasked with scrutinizing and reporting on the exercise of delegated powers by the executive branch. They ensure the government is acting within the legal boundaries set by Parliament when creating rules, regulations, etc.

Committee on Government Assurances (A) focuses on tracking the implementation of assurances, and promises made by the government in Parliament.

Rules Committee (C) deals with framing rules for the smooth functioning of the Houses of Parliament (Lok Sabha and Rajya Sabha).

Business Advisory Committee (D) allocates time for different kinds of legislative and other business of the House.

Therefore, only the Committee on Subordinate Legislation directly addresses the scrutiny of delegated powers.
