The prefix Helio- indicates which of the following?

Explanation:
Helio- comes from the Greek Helios, meaning the sun. It’s used to form terms that relate to the sun, such as heliotherapy (treatment using sunlight) or heliocentric (sun-centered). That’s why it points to the sun. The other ideas—moon, star, or light—have different roots (luna- for moon, astro- or stell- for star, photo- or lumin- for light), so they don’t fit helio- even though they might appear related in everyday language.
