Which reading indicates tachycardia in a typical adult?

Explanation:
Tachycardia means a resting heart rate over 100 beats per minute in adults. Among these readings, the young adult showing 104/min is the one that crosses that threshold, indicating tachycardia. The infant’s 132/min is high for an infant but falls within typical pediatric ranges, where resting rates are often above adult values. The preschooler’s 108/min is also within normal pediatric limits (not tachycardia for that age). The older adult’s 96/min stays within the normal adult range. So the value that indicates tachycardia for a typical adult is the 104/min in a young adult.
