The correct answer is A, as during his election campaign in 1988, George H.W. Bush promised not to raise taxes.
Vice President George H. Bush was supported by President Reagan and promised to follow Reagan's policies if elected, albeit in a more moderate way. As every Republican candidate, he pronounced himself against tax raising.
But once in office, President Bush broke this promise: after a struggle with Congress, he signed an increase in taxes that Congress finally approved. In the wake of economic concerns, he lost the 1992 election against Bill Clinton.
