Answer:
D - High Arousal; Low Arousal
Step-by-step explanation:
The Yerkes Dodson law explains the relationship between arousal and performance. It was posited by Robert M. Yerkes and John Dillingham Dodson in 1908.
The law asserts that there is a direct relationship between arousal and performance. An increase in arousal up to a certain level will enhance performance, and once the optimal threshold is exceeded, performance will begin to decline.
Thus arousal should be kept at a midpoint as too little causes boredom, and too much causes hyperactivity, so moderate arousal is optimal.
A simple task requires higher arousal because it uses less cognitive function and brain power thus higher arousal is required to keep interest; while a difficult task requires low arousal since it requires higher cognitive function, it requires lots of focus and higher arousal is not good for intense focus as it causes hyperactivity.
