According to the yerkes-dodson law, the relationship between arousal and performance can be described by a(n)

a. ? positive linear function (more arousal leads to better performance)

b. ? positive exponential function (more arousal leads to better and better performance; a lot of arousal leads to tremendously good performance)

c. ? inverted u-shaped function (more arousal leads to better performance, but only up to a point; too much arousal can hinder performance)

d. ? negative linear function (less arousal leads to better performance)
