Which of the following crises occurred during the presidency of Jimmy Carter (1977-1981)?

Jimmy Carter's presidency (1977-1981) was marked by several significant international and domestic challenges. The Iran Hostage Crisis began in November 1979 when American diplomats and citizens were taken hostage in Tehran, lasting 444 days and profoundly impacting U.S. foreign policy. The Global Oil Crisis, particularly the 1979 energy crisis, saw rising oil prices and gasoline shortages, contributing to economic instability. Following the Soviet invasion of Afghanistan in December 1979, the U.S. under Carter initiated support to Pakistan to aid Afghan mujahideen, a policy that intensified later. Therefore, all listed events occurred during his term.

• A: Iran Hostage Crisis is correct, a defining event of his presidency.
• B: Global Oil Crisis (specifically the 1979 crisis) is also correct, impacting the U.S. economy.
• C: U.S. support to Pakistan after Soviet invasion of Afghanistan is correct, a key foreign policy response.
• D: All of these is the accurate answer as all three events transpired during Jimmy Carter's time in office.
