B. is the answer to the problem- let me know if it was right I'm pretty certain it is.
The Greek god is Dionysus; he was the youngest of the Greek gods, supposedly and was the last to be admitted into Mt. Olympus.
The independent clause is "WE ARE NOT EATING ON THE PATIO" the reason why, is because the second part of the sentence cannot stand on its own, due to the fact it has a because in it. because is a transition word.
I think it is the second one! I am pretty sure!
