• C.
• D.

Answer: (D)

Verified step by step guidance

1. Analyze the question to determine the energy systems used during different sections of the 1500-meter race. The energy systems include ATP-CP, Glycolysis, and Aerobic metabolism.
2. Review the provided charts to identify the correct sequence of energy systems used during the race. Each chart represents a different combination of energy systems for the 0-100m, 100-1000m, and 1000-1500m sections.
3. Understand the characteristics of each energy system: ATP-CP is used for short bursts of energy (0-10 seconds), Glycolysis is used for moderate-duration activities (up to 2 minutes), and the Aerobic system is used for sustained, long-duration activities.
4. Compare the charts to the physiological demands of a 1500-meter race. The race starts with a short burst of energy (ATP-CP), transitions to moderate energy production (Glycolysis), and ends with sustained energy production (Aerobic system).
5. Select the chart that matches the correct sequence: ATP-CP for 0-100m, Glycolysis for 100-1000m, and Aerobic system for 1000-1500m. This chart aligns with the energy demands of the race.
