The correct answer is C. Commonwealth Games scam.
The Shunglu Committee was a committee appointed by the Government of India to inquire into the alleged irregularities and corruption in the preparation and conduct of the 2010 Commonwealth Games in Delhi. The committee was headed by Justice M.M. Shunglu, a former Chief Justice of the Punjab and Haryana High Court.
The committee submitted its report in 2011, making a number of recommendations for improving the management of public events in India. The report was highly critical of the organizing committee of the Commonwealth Games, and found that there had been widespread corruption and mismanagement.
The Shunglu Committee’s report was a major embarrassment for the Indian government, and led to the resignation of several senior officials. The report also led to a number of reforms being implemented in the management of public events in India.

Option B is incorrect because the management of co-operatives is done by the National Cooperative Development Corporation. Option D is incorrect because the insurance sector reforms were done by the Insurance Regulatory and Development Authority of India.
