The correct answer is option 2, Apollo-13. This mission was intended to be the seventh crewed mission in the Apollo space program. However, it encountered a critical failure during its journey to the moon. Approximately 56 hours into the mission, an oxygen tank in the Service Module exploded, causing a loss of electrical power and other vital systems.

As a result of the explosion, the mission had to be aborted, and the crew had to rely on the Lunar Module as a "lifeboat" to provide life support and propulsion needed to return them safely back to Earth. The crew, consisting of James A. Lovell Jr., John L. Swigert Jr., and Fred W. Haise Jr., successfully executed a series of maneuvers and returned to Earth, splashing down in the Pacific Ocean.

Apollo-12, option 1, successfully reached the moon and completed its mission objectives. Apollo-15, option 3, and Apollo-17, option 4, were also successful moon landing missions.
