The Shunglu Committee was appointed by the Prime Minister for a specific purpose. Option 1 suggests that their task was to draft the Jan Lokpal Bill. The Jan Lokpal Bill is a proposed anti-corruption legislation that aims to create an independent ombudsman to investigate and prosecute cases of corruption. However, the Shunglu Committee was not responsible for drafting this bill, so option 1 is incorrect.

Option 2 states that the committee was appointed to look into corruption charges in the conduct of the Commonwealth Games. The Commonwealth Games were marred by allegations of corruption and financial irregularities. The Shunglu Committee was indeed appointed to investigate these charges and ensure accountability, making option 2 the correct answer.

Option 3 suggests that the committee was appointed to investigate the telecom scam. The telecom scam refers to the irregularities and corruption in the allocation of 2G spectrum licenses. However, the Shunglu Committee was not specifically tasked with investigating this scam, so option 3 is incorrect.

Option 4 implies that the committee was appointed to inquire into phone-tapping amid a corporate lobbyist scandal. While phone-tapping and corporate lobbyist scandals have been the subjects of independent investigations in India, the Shunglu Committee was not specifically appointed for this purpose. Therefore
