Amaintain a vacuum in the shell of the feed water heater
Bprovide a point of admission for the steam air heater drains
Cprovide a point of admission for the L.P. bleed steam
Ddrain condensate from the feed water heater to the main condenser
AI Explanation

The correct answer is A) maintain a vacuum in the shell of the feed water heater. The connections labeled "A" in the illustration are used to maintain a vacuum in the shell of the feed water heater. This is necessary to improve the efficiency of the heat transfer process, as a vacuum helps to prevent the formation of steam bubbles that could reduce the effectiveness of the heat exchange. The other answer choices are incorrect because they do not accurately describe the purpose of the "A" connections in the feed water heater system. Options B, C, and D describe different functions or connections within the overall steam or condensate system, but they are not specifically related to the vacuum maintenance in the feed water heater shell.
