The correct answer highlights the requirement that thermostats, when used as a disconnecting means for fixed heating equipment, must be positioned within sight of the equipment. This ensures that a person can clearly see both the thermostat and the heating equipment it controls.

Having the thermostat in sight allows for immediate control in the event of an emergency or when maintenance is needed. It enables quick disconnection without the need for the operator to leave the vicinity of the equipment, reducing response time and enhancing safety.

This placement aligns with safety standards and codes, which emphasize the importance of visibility to prevent accidents or mishandling when controlling heating systems. In contrast, the other choices do not address this crucial aspect of safety and accessibility, making them less suitable for the intended function of the thermostat in this context.
