Which sentence uses the passive voice?

Dad served in the army in Hawaii for two years.
His work in the Munitions Unit offered many challenges. A storage bin was once blown up because of carelessness.
They had to put out a large fire on the base, that day.

Answer 1

i believe the answer is C) A storage bin was once blown up because of carelessness. as we can see this sentence states "was once blown up" was is a passive word. meaning past tence, so the answer is more and likely that.
