Who was the teacher of Achilles that traded his immortality for death?

The correct answer is B, Chiron. Chiron was a wise and highly respected centaur in Greek mythology, known for his exceptional skills in medicine and training heroes. Unlike other centaurs, who were often depicted as unruly, Chiron was characterized by his intelligence, kindness, and dedication to teaching. He educated several famous figures, including Achilles, Hercules, and Asclepius.

The story of Chiron trading his immortality for death is a poignant one. In myth, Chiron was accidentally wounded by an arrow poisoned by Hercules. Unable to heal his own injury yet unable to die due to his immortality, Chiron made the noble choice to trade his immortality to save Prometheus, who was punished by Zeus. This sacrifice highlights his selflessness and reinforces his role as a mentor and protector of heroes.

The other figures mentioned have their own distinct stories that do not align with this specific context. For example, Prometheus is known for his act of stealing fire from the gods for humanity, Mentor was a companion of Odysseus and often associated with the role of wise adviser, and Aesculapius is the god of healing and medicine, focused more on curing than on the theme of immortality and sacrifice
