The correct answer is (b) 10.
The Public Accounts Committee (PAC) is a standing committee of the Parliament of India. It is one of the oldest standing committees of Parliament, having been constituted in 1921. The PAC is responsible for examining the accounts of the Union Government and its subordinate offices. It also examines the reports of the Comptroller and Auditor General of India (CAG) on the accounts of the Union Government.
The PAC consists of 15 members, 10 of whom are elected from the Lok Sabha and 5 of whom are elected from the Rajya Sabha. The members of the PAC are elected by the respective Houses of Parliament. The Chairman of the PAC is elected by the members of the PAC from among themselves.
The PAC is a powerful committee and has the power to summon officials of the Union Government and to examine them on oath. It also has the power to call for documents and records from the Union Government. The PAC submits its reports to the Parliament, which are then debated and discussed in the Houses of Parliament.
The PAC has played a significant role in ensuring accountability of the Union Government to the Parliament. It has also been instrumental in bringing about reforms in the functioning of the Union Government.
The other options are incorrect because they do not represent the correct number of members elected from the Lok Sabha for Public Account Committee.
