Answer
In response to aerobic training, the resting heart rate is likely to decrease. This is due to improved cardiovascular efficiency, where the heart becomes stronger and pumps more blood per beat.

Answer
Haemoglobin levels typically increase with aerobic training. This adaptation helps to enhance oxygen transport in the blood, allowing for better endurance performance.

Answer
Resting blood pressure is generally expected to decrease as a result of aerobic training. Improved heart efficiency and vascular health contribute to lower resting blood pressure.

Answer
Based on the adaptations mentioned, the most likely physiological responses to aerobic training would align with option (C): Resting heart rate decreases, haemoglobin levels increase, and resting blood pressure decreases.
