The best and most correct answer among the choices provided by the question is the second choice "The Obama administration withdrew most troops from Iraq and prepared for troop withdrawal from Afghanistan."
For all of Obama’s efforts at rapprochement with much of the world, he—like George W. Bush—was a wartime president. With the situation in Iraq continuing to improve and the target date for ending U.S. combat operations there approaching, in February 2009 Obama increased the U.S. military presence in Afghanistan to 68,000 troops. Throughout his presidential campaign he had argued that the focus of U.S. military efforts should be in Afghanistan rather than Iraq, and, with the resurgence of the Taliban in Afghanistan, the military requested that Obama deploy an additional 40,000 troops there. After carefully weighing the situation for three months, Obama choose to send an additional 30,000 troops, a decision that was criticized by many in his party.
