The correct answer is A, as weapons of mass destruction were not found in Iraq, which makes the statement incorrect.
In 2003, the United States invaded Iraq after repeated accusations of possessing weapons of mass destruction (which were never found, nor was their existence proven), a military operation that Bush described as part of his "war against terrorism". As time went by, and without these weapons of mass destruction being found, the popularity and approval of the citizenship towards Bush began to fall.
In 2007 Alan Greenspan, former president of the Federal Reserve, said in his memoir that the real motive for invading Iraq was not the publicly expressed reasons, which were related to the alleged weapons of mass destruction and to end the alleged relationship between the Iraqi Baathi government and the al Qaeda guerrilla organization; but to control the oil reserves of that country.
