Which term describes zones located in green band operation?

Explanation:
The idea here is using color-coded operating ranges, where green marks the normal, safe, or acceptable performance zone. Zones that fall within this green band are described as being in green band operation because the term literally names the color-coded range being met. This color-coding helps operators quickly gauge status: green means things are within spec and proceeding normally, while yellow or red indicate caution or danger, respectively. The other terms refer to different concepts (a type of indicator, a general indication, or an unrelated physical phenomenon) and don’t describe the classification of zones by their operating band.
