Answer: D. "Let's get going!" Ginnie shouted. "It's getting dark!"
Step-by-step explanation:
There must be quotation marks around what is being said.
Because Ginnie shouted there must also be en exclamation mark after what she's saying.
A period ends a sentence that provides information or states a fact or opinion. "Ginnie shouted" is the fact being stated.
I hope this helps :)
