D is correct: Shows the natural progression of energy systems as intensity/duration increases

Other Options:

A is incorrect: ATP-PCr is the initial energy system
B is incorrect: ATP-PCr is the initial energy system and aerobic takes longer to become predominant
C is incorrect: Glycolytic precedes Aerobic for moderate-high intensity
