Explanation

Option C is correct because hysteresis allows the circuit elements adequate time to saturate and desaturate, ensuring stable switching behavior. While noise immunity (Option D) is a benefit of hysteresis, the primary reason is to accommodate the time required for device saturation. Options A and B are not the main reasons for incorporating hysteresis in a Schmitt trigger.
