Step-by-step explanation:
The mythical god believed to promote healthcare in ancient times was Asclepius, who is not mentioned as an option in the student's question. Asclepius, the god of medicine and healing, was associated with therapeutic and medicinal arts in Greek mythology. His attributes included the staff and the serpent, which remain symbols of medicine today. Asclepius was the son of Apollo, and was revered at healing temples, called Asclepieia, where people would go to seek cures for their ailments. Though the question does not accurately list Asclepius, the closest match provided in the answer choices would be Apollo (option A), as he is linked to the healing arts through his son Asclepius. Apollo himself was the god of several domains, including the sun, music, and prophecy, but not specifically healthcare.
