Your Beagle, Nolan, Has Recently Acquired the Habit of Howling

Your beagle, Nolan, has recently acquired the habit of howling anytime the ice maker in your freezer comes on. You suspect Nolan does not like the noise it makes and would like to correct his behavior through nonreinforcement. Which approach best describes a method of nonreinforcement that might help you break Nolan of his howling?

A) Ignore Nolan when he begins to howl at the ice maker and assume he will eventually adapt to the noise.
B) Spank Nolan on the backside and tell him he is a bad dog anytime he howls at the ice maker.
C) Give Nolan a dog treat anytime the ice maker comes on and he does not howl at it.
D) Shut off the ice maker so it no longer turns on and makes the noise that upsets Nolan.
