Achild is punished and temporarily stops his or her well-established bad behavior. however, the child soon goes back to acting badly. this is probably because

Punishment is known only to temporarily suppress or inhibit a behavior.

The reason why "Punishment is known only to temporarily suppress or inhibit a behavior" is the correct answer because punishment is not a long-term effect on a child.

Punishment is only temporary to stop some kind of behavior. For example, a kid is running around the house and messing everything up, so the parents put the kid on timeout and made the kid sit down next to the corner of the room for 5 minutes. After the timeout (punishment), the kid goes on to be free again and will start doing whatever it's doing again.

The timeout that the parents gave the kid only stopped the kid from messing up the house for a brief moment. The kid could just sit there for 5 minutes and think of other stuff, instead of thinking what they did was wrong

In order for the parents to permanently keep the kid from messing up the house, they should give the kid a talk on what they're doing is wrong.
