The correct answer indicates that the primary function of handholds on a boiler is to facilitate easy inspection of the boiler. Handholds are specifically designed openings on the boiler that allow operators and maintenance personnel to access the internal components of the boiler for visual inspections and assessments. This access is crucial for ensuring that the boiler operates efficiently and safely, as it enables the detection of potential issues, buildup of deposits, or deterioration of materials.

Having easy access through handholds helps maintain the integrity and functionality of the boiler. Regular inspections can prevent larger issues from developing, ultimately ensuring the safety and efficiency of the operation. While transportation and maintenance access are important considerations in the overall design, the specific purpose of handholds is closely linked to inspection tasks essential for the boiler's operation. Regulating pressure is a function achieved through other components and controls within the boiler system, further distinguishing the roles of handholds from those other functions.
