Answer:
The correct answer is letter "A": The next to last flat is the same as the key signature.
Explanation:
The key signature is the next to last flat for key signatures of flats. This is the key to E flat since E flat in the main signature is the next to last flat. This is D flat's secret since D flat in the main signature is the next to last flat. That's why it's the D flat key.
