Final answer:
In Greek mythology, Hyperion is often associated with the Sun and is the father of Helios, but the epithet 'the all-seeing' is not typically used for Helios.
Step-by-step explanation:
Helios is sometimes described with the epithet “the all-seeing”. Among the options provided, a) Panoptes b) Hyperion c) Phanes d) Helios_APX, the correct answer is b) Hyperion. Hyperion is one of the twelve Titan children of Gaia (Earth) and Uranus (Sky) in Greek mythology. Often associated with the Sun, he is considered the father of Helios (the sun god in later mythology). However, the epithet “the all-seeing” is not commonly used for Helios; instead, it is often applied to figures like Argus Panoptes, who had multiple eyes. In the context of this question, the reference to Helios being “all-seeing” could be poetic rather than a direct reference to a standard ancient text or epithet.
