I agree, (D) is simply a bad match for the argument. Oftentimes, questions like these are sort of like matching questions. Your job is to choose the one that best matches what happens in the argument.
In the original:
Facts:
doctors decide the course of treatment
doctors get paid per procedure
Conclusion:
doctors frequently call for treatment only to make $
The key words in the conclusion are, of course, frequently and only. This is where the author goes wrong, as we have no evidence for this.
(B) match it up!
"performance of actions" = "administering treatments"
The key language here is on no basis other than two things: incentive ($), and opportunity (sole discretion).
(D) We can stop at "arbitrarily" and eliminate the choice without reading any further. There's nothing arbitrary about it -- according to our author, they're in it for the money.
