The correct answer is B. The Iran-Contra affair was the greatest scandal of the Reagan administration.

Explanation:

The Iran-Contras scandal was a foreign policy scandal in the United States in the 1980s. In 1986, the Reagan administration was found to be selling arms illegally to Iran, which was fighting Iraq in the Iraq-Iran war, and to fund the anti-government Insurgent insurgents in Nicaragua. However, Iran was on the list of countries supporting terrorism at the time, so it was not possible to export weapons there. With this move, the administration was promised to secure the release of US hostages held in Lebanon. The Iran-Contras affair was the largest American political affair of the 1980s. Reagan said he knew nothing and called for an independent investigation.

A case was brought before the International Court of Justice in 1986, Nicaragua vs. United States of America. The Court ruled that the United States had violated international law by supporting the Contra and laying offshore mines off Nicaraguan ports. However, the United States vetoed the decision at the UN Security Council, so it did not have any effect.
