Final answer:
The correct answer is option d. The chairman is appointed by the Speaker of the Lok Sabha, it can examine reports from the CAG, and ministers cannot be members of the committee.
Step-by-step explanation:
The question pertains to the Committee on Public Undertakings in India, and the validity of statements concerning its operations. The statements that need verification are: the Chairman of the committee is appointed by the Speaker of the Lok Sabha, the committee can examine reports of the Comptroller and Auditor General (CAG), and ministers cannot be members of the committee.
Firstly, the Chairman of the Committee on Public Undertakings is indeed appointed by the Speaker of the Lok Sabha, not the Chairman. This pertains to the role of the Speaker in managing parliamentary committees. Secondly, the committee does have the authority to examine the reports prepared by the CAG that pertain to public sector undertakings.
Lastly, it is correct that a minister cannot be appointed as a member of this committee. This is to maintain the committee's independence and ensure unbiased oversight and accountability. Thus, all three statements are accurate, making the answer (d.) 1, 2 and 3.
