ADiaphragm pump
BReciprocating pump
CCentrifugal pump
DRotary pump
AI Explanation
The correct answer is C) Centrifugal pump. In a hydronic heating system, a centrifugal pump is invariably used as the circulator. Centrifugal pumps are well-suited for this application because they can generate the necessary pressure to circulate the heated water or other fluids through the system's pipes and radiators. The other options are not commonly used as circulators in hydronic heating systems. Diaphragm pumps and reciprocating pumps are more often used for positive displacement applications, while rotary pumps are not as efficient for the high-volume, low-pressure requirements of a hydronic heating system.
