The correct answer highlights that the range in a control system is typically fixed and non-adjustable. In many control setups, the range defines the limits between which a variable can operate. For example, in a temperature control system, the range may specify the minimum and maximum temperatures that can be detected or controlled. This range is predetermined based on the system's design specifications and is not meant to change during operation, which differentiates it from other control settings like set points, differentials, or cut-ins, which may have adjustability based on the desired operational parameters.

Set points, for instance, may be adjusted according to the specific needs of the process or system being controlled. Similarly, differential settings can also be modified to manage how sensitive a control system should be in maintaining its set point. Cut-ins might be adjusted based on operational requirements, such as configuring the point at which a device is activated. Thus, the fixed nature of the range makes it a critical component in defining operational limits within a control system.
