When arnold misbehaves, his parents have him sit alone for a few minutes in the laundry room, which is quiet and away from the rest of the family. arnold's parents are using?

Arnold's parents are using "time-out".

"Time out" is a sort of discipline that guardians and instructors use for little kids. On the off chance that a youngster acts up, you can send them to "time out". That implies that they need to sit alone and with no toys to occupy them for a couple of minutes. 

Ithink the answer is d. the lower appellate and trial courts in the state.
