Know its a or b but I dont know which one can anyone help????

Answer 1

A. his muscles will undergo anaerobic respiration

anaerobic respiration means that there is not enough oxygen going through the blood into the muscles and the body has to respirate through other things such as lactic acid buildup. this respiration is most suitable for short, intense workouts because your body cannot thrive on anaerobic respiration for too long
