Aauxiliary feed pump
Bmain feed pump
Ccondenser vacuum drag line
Dfeed booster pump
AI Explanation
The correct answer is C) condenser vacuum drag line. In a closed feed system, makeup feed water is brought into the system via the condenser vacuum drag line. The condenser vacuum drag line is connected to the condenser and uses the vacuum created by the condenser to draw in makeup water and add it to the closed feed system. The other answer choices are incorrect because: A) The auxiliary feed pump is used to supply feed water to the boiler, not bring makeup water into the closed feed system. B) The main feed pump is also used to supply feed water to the boiler, not bring in makeup water. D) The feed booster pump is used to increase the pressure of the feed water, not to bring in makeup water.
