The correct answer is B, as the Bay of Pigs Invasion was planned as a secret invasion of Cuba led by the CIA.
The Bay of Pigs Invasion was the failed attempt to overthrow Fidel Castro's regime, put in place by a group of Cuban exiles and mercenaries, trained by the CIA, who planned to conquer Cuba starting from the invasion of the south-west of the island.
The operation, scheduled by CIA director Allen Welsh Dulles during the Eisenhower administration, was launched in April 1961, not even three months after John F. Kennedy took office as President. The Cuban armed forces, equipped and trained by the pro-Soviet nations of the Eastern bloc, defeated the invasion force in three days of fighting, on April 19, 1961.
