Answer:
Option C. Explicit.
Step-by-step explanation:
The adjective explicit is defined as something stated clearly and in detail, leaving no room for confusion or doubt.
Sometimes a writer might leave implicit statements in the text with the objective of keeping the reader invested in the story, figuring out the story for themself. However, if the objective is to explain a character or setting directly to the reader, then it is best to make an explicit description knowing that it won't leave any details implied for the reader to interpret themself.
