A pulse rate of 60 beats per minute for a child typically falls outside the normal range for children aged 6 to 15, where the average resting heart rate generally ranges from 70 to 110 beats per minute. Therefore, saying that the child's pulse rate is normal for adults but low for children accurately reflects the physiological differences between these age groups. Adults often have a lower resting heart rate than children due to various factors including size, efficiency of the heart, and overall fitness levels.

In the context of the other options, while some children may naturally have lower pulse rates, consistently measuring 60 beats per minute would generally indicate a rate on the lower end for the pediatric population, not within the normal range for children of that age. Additionally, there isn't sufficient evidence to conclude that a pulse rate of 60 indicates an active lifestyle, as heart rate can also reflect other factors such as health status, stress levels, and fitness.
