Like one for exercise or hospitals one for exercise is to see how fat your heart beats when you mover around and one for hosptials is to make sure patients have normal health heart rates or to make sure they are still alive
Is there any information to back this up? Like how do the non-spanked peers behave?
Based on the lack of information I'd say it's A or B.
A, because if the non-spanked peers are well behaved she might want to be more obedient to avoid spankings like them.
B, because she might find it unfair that she is the only one in her class or group of peers who receives spankings.
I don't think it would be c or d.
