Which of the following is an assumption on which the argument relies?

Conclusion from statement: patient should take care to choose the specialist who has performed that procedure the greatest number of times
Why? (from statement): patients facing major medical procedures should not have to concern themselves with whether or not the selected surgeon is adequately skilled

(A) The specialist who has performed a medical procedure the greatest number of times has better-than-average faculty with that procedure.
- Correct

(B) If a patient experiences anxiety prior to undergoing a certain medical procedure, he or she is less likely to successfully recover from the procedure.
- Out of Scope. Not a discussion of recovery

(C) Most patients do not take care to select specialisist on the basis of the specialist's experience with the medical procedure involved.
- Irrelevant. No mention of claims that patients do not take care to select specialist

(D) Patients should disregard the recommendations of their regular physicians when deciding which specialist to select for an unusual medical procedure.

(E) Only the specialist who has performed a specific medical procedure the greatest number of times is capable of carrying out that procedure successfully.
- Partial scope but misleading due to the word ONLY.
