The correct choice is associated with the function of ensuring the water quality within the boiler system. Carryover occurs when water and impurities are carried into the steam due to abrupt changes in water levels or poor water treatment processes. Effective feedwater treatment is vital for preventing carryover because it removes impurities, such as dissolved solids and other contaminants, before the water enters the boiler. By controlling these impurities, the treatment maintains the necessary quality of water, which in turn reduces the potential for carryover and thus protects the boiler's efficiency and longevity.

In contrast, while water levels are important for overall boiler operation, they do not specifically prevent carryover; they merely indicate whether the water is at appropriate levels. Blowdown valves do play a role in maintaining water quality by allowing operators to remove concentrated impurities from the boiler water, but they are more related to managing the concentration of solids rather than directly treating the feedwater before it enters the system. Soot blowers are designed for cleaning boiler tubes that accumulate soot and do not have a direct influence on the prevention of water carryover. Therefore, the focus on feedwater treatment directly addresses the core concern of preventing carryover by ensuring that the water entering the boiler is clean and properly conditioned.
