Who were the two individuals primarily responsible for the Oklahoma City bombing?

The correct answer is based on the fact that Timothy McVeigh and Terry Nichols were convicted for their roles in the Oklahoma City bombing, which took place on April 19, 1995. McVeigh was the principal architect of the attack, detonating a truck filled with explosives outside the Alfred P. Murrah Federal Building, leading to the deaths of 168 people, including many children and infants. Terry Nichols assisted McVeigh in planning and executing the bombing. Both men were motivated by a radical anti-government ideology, which they believed justified their violent actions.

The other options mention individuals or groups who were not involved in the Oklahoma City bombing. Osama bin Laden and Ayman al-Zawahiri were prominent figures in terrorism and were leaders of al-Qaeda, primarily associated with attacks against the United States, but not connected to the Oklahoma City incident. Robert Fisk and Edward Said are journalists and scholars known for their works on Middle Eastern politics and culture, with no association with domestic terrorism in the United States. Bill Clinton and Al Gore served as President and Vice President of the United States at the time of the bombing but were not implicated in the act itself. Thus, the focus on McVeigh and Nichols accurately identifies the individuals held responsible for
