B50%

D0%
AI Explanation
The correct answer is A) 100%. In a multi-box refrigeration system with a compressor designed with six of its eight cylinders able to be controlled for variable load conditions, if all of the reefer boxes are currently feeding, then all six of the variable load cylinders will be in use, resulting in 100% of the total number of compressor cylinders being loaded after start up. The other answer choices are incorrect because: B) 50% would only be true if half of the variable load cylinders were being used. C) 25% would be incorrect as it does not account for the full six variable load cylinders being utilized. D) 0% would be incorrect as at least the six variable load cylinders would be in use.
