D) The energy will always be greater than the initial energy quality.

Quizplus · Accepted Answer

The quality of energy available after any heat-to-work conversion is performed will always be less than the initial energy quality due to the second law of thermodynamics, which states that some energy will always be lost to heat during the conversion process. Therefore, choice A is the correct answer.
