Junctional Tachycardia rate

Explanation:
The main idea here is that tachycardia is defined by a rate that’s faster than normal. A junctional tachycardia is a fast rhythm originating from the AV junction, so its defining feature is a heart rate at or above 100 beats per minute. Values lower than that describe slower AV-junction rhythms—normal junctional rhythm (about 40–60 bpm) and accelerated junctional rhythm (about 60–100 bpm). Because the question asks for the rate that defines junctional tachycardia, the threshold is 100 bpm or more. In clinical context, you may see this with a narrow QRS complex and P waves that are absent or retrograde, but the key distinguishing factor here is the rate being at least 100 bpm.
