What constitutes a reactive NST?

Explanation:
A reactive NST is shown when the fetal heart rate accelerates in response to fetal movements, indicating a healthy autonomic nervous system and adequate oxygenation. The standard criterion is two or more accelerations, each at least 15 beats per minute above baseline and lasting at least 15 seconds, occurring within a 20-minute window. The option with two accelerations meeting those thresholds within the 20-minute period fits this pattern precisely, making it the correct example of a reactive NST. It demonstrates the necessary two distinct accelerations that confirm fetal well-being.
