A is correct: ATP-PCr depletes within 10 seconds, contributing minimally to 30-second rallies

Other Options:

B is incorrect: 30s rallies heavily utilise glycolytic system
C is incorrect: Aerobic system aids recovery between rallies
D is incorrect: Systems contribute unequally – glycolytic dominates rallies, aerobic dominates recovery, ATP-PCr contributes least
