To determine the correct answer, we need to analyze the historical events during the 1950s and the involvement of the Central Intelligence Agency (CIA) in engineering political coups.

The CIA is known to have been involved in several covert operations during the Cold War era, aimed at promoting pro-American governments and countering the spread of communism. Two significant coup d'état operations that occurred during the 1950s were in Iran and Guatemala. Let's examine the options based on this information:

A.) Iraq and Nicaragua: There is no evidence of CIA-engineered coups in Iraq and Nicaragua during the 1950s.

B.) Libya and Costa Rica: There is no evidence of CIA-engineered coups in Libya and Costa Rica during the 1950s.

C.) Lebanon and El Salvador: There is no evidence of CIA-engineered coups in Lebanon and El Salvador during the 1950s.

D.) Iran and Guatemala: The CIA was involved in two major coups during the 1950s. In 1953, the CIA organized Operation Ajax in Iran, which resulted in the overthrow of Iranian Prime Minister Mohammad Mosaddegh and the reinstatement of Shah Mohammad Reza Pahlavi. In 1954, the CIA orchestrated Operation PBSUCCESS in Guatemala, which overthrew democratically-elected President Jacobo Arbenz and installed a pro-American military government.

E.) Egypt and Cuba: There is no evidence of CIA-engineered coups in Egypt and Cuba during the 1950s.

Based on the analysis, the correct answer is option D.) Iran and Guatemala.
