正确答案是C吗？我怎么觉得是B？？求解释

Q45[c1]. Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-rays because their orthopedists are concerned about possibly having misjudged the stability of the fracture. When a number of follow-up x-rays were reviewed,

however, all the fractures that had initially been judged stable were found to have healed correctly. Therefore,it is a waste of money to order follow-up x-rays ofankle fractures initially judged stable.[c2]

Which of the following, if true, most strengthens the argument?

(A) Doctors who are general practitioners[c3] rather than orthopedists are less likely than

orthopedists to judge the stability of an ankle fracture correctly.

(8)[c4] Many ankle injuries for which an initial x-ray is ordered are revealed by the x-ray not to involve any fracture of the ankle.

(C)X-rays of patients of many different orthopedists working in several hospitals were reviewed. C[c5]

(D) [c6]The healing of ankle fractures that have been surgically repaired is always checked by means of a follow-up x-ray.

(E)[c7] Orthopedists routinely order follow-up x-rays for fractures of bones other than ankle bones.

[c1]推理链：通常踝关节骨折都是稳定的，不需要手术，但矫形外科医师考虑到错诊骨折稳定性的可能性，会让病人拍x光但是所有的踝关节骨折都很稳定直到痊愈结论


[c2]因果型结论


[c3]无关


[c4]没有support


[c5]调查有效性，数据具有代表作用



[c6]无关，文中说的是一开始用x光


[c7]无关

I double checked. The answer should be C for sufficiency of data.

How to define the word "reviewed" here?
