d) George W. Bush

George W. Bush, the 43rd President of the United States, is the only U.S. President to hold a Master of Business Administration (MBA) degree, which he earned from Harvard Business School. Bush’s educational background in business was unique among presidents and influenced his approach to policy and governance. His presidency, which spanned from 2001 to 2009, was defined by significant events such as the September 11 attacks and the subsequent War on Terror, as well as the 2008 financial crisis. Bush’s MBA background provided a distinct perspective in his leadership and decision-making processes.
