The Members of Parliamentary Committees are appointed or elected on a motion made and adopted or nominated by the Speaker of the Lok Sabha or the Chairman of the Rajya Sabha.
According to the Rules of Procedure and Conduct of Business in Lok Sabha and Rajya Sabha, members of various parliamentary committees can be constituted in several ways. This includes election by the House on a motion (as is often the case for financial committees like the Public Accounts Committee) or nomination by the presiding officer (Speaker in Lok Sabha, Chairman in Rajya Sabha) (as is common for many standing and ad hoc committees).
The specific method of constitution varies depending on the type of committee as defined in the rules of each House. Some committees are purely nominated by the presiding officer, some are elected, and others might follow a combination or specific process involving both the House and the presiding officer. Option D provides the most accurate general description covering the different methods used.
