Answer:
The correct answer is Goddess.
Step-by-step explanation:
Goddess is a descriptive title that is also a noun (a thing). Artemis is a proper noun, and these must always be capitalized. Greek is an adjective, but also references a culture, so it is a proper noun. Therefore, it must be capitalized. We precedes the rest of the sentence, so it must also be capitalized. Therefore, by using POE (process of elimination), you can determine that Goddess is the word that should be lowercase.
