This requires matching each corporation with its actual CEO. Rajat Gupta was indeed managing director of McKinsey & Company. Arun Sarin was CEO of Vodafone. Arun Netravali was president of Bell Labs. However, IBM's CEO during the relevant period was Sam Palmisano (2000-2005) and later leaders, not Rajesh Hukku (who led an Indian subsidiary). Therefore C is the incorrect pair.
