A. Afghanistan claimed responsibility for the September 11 attacks.

The United States chose to go to war in Afghanistan primarily because Afghanistan refused to surrender Osama bin Laden to the United States (Option C). Bin Laden was the leader of the terrorist group known as Al-Qaeda, which claimed responsibility for the September 11 attacks (Option A). The United States considered this refusal as a direct threat to its national security. Afghanistan was providing a safe haven for Al-Qaeda and allowing them to operate within its borders. The United States wanted to eliminate Al-Qaeda and dismantle their infrastructure, which led to the decision to go to war in Afghanistan.

The correct answer is A. Afghanistan claimed responsibility for the September 11 attacks.

To arrive at this answer, one must understand the context of the events that took place in the aftermath of September 11, 2001. On that day, terrorist attacks were carried out on the United States by the extremist group Al-Qaeda, which was led by Osama bin Laden. The attacks resulted in the deaths of thousands of innocent civilians.

Following these attacks, the U.S. government, under President George W. Bush, declared a global war on terror. Soon after, it was discovered that Al-Qaeda had a significant presence in Afghanistan, where they were given sanctuary by the Taliban government, which ruled the country at the time.

Given the magnitude of the attacks and the fact that they were planned and orchestrated from Afghanistan, the United States believed it was necessary to take action against both Al-Qaeda and the Taliban regime in Afghanistan. Consequently, the U.S. launched a military campaign, known as Operation Enduring Freedom, with the primary objective of removing the Taliban from power and destroying Al-Qaeda's infrastructure.

In summary, the United States chose to go to war in Afghanistan because Afghanistan, specifically Al-Qaeda, claimed responsibility for the September 11 attacks, making it imperative for the U.S. to take action in order to eliminate the threat and bring justice to the perpetrators.
