Costly X-rays often not needed, the OT rules were developed to aid in a doctor’s decision as to whether a patient with foot pain should be offered an X-ray, since only 5% of patients before the rules actually had fractures when X-rayed.

I've voted for B here.
A is incorrect for the way it starts. "Costly X-rays often not needed" looks like an out of place modifier?
E - The last bit "when X-rayed actually had fractures before the rules’ development" does not seem to appreciate the development of OT rules.
D - Again seems to be a modifier error.
Between B and C. I chose B over C because B puts the main clause / sub clause combo in the right order.. gives me the maximum clarity at least.
Experts please correct me.

+1 for B.
Searched in other forums. OA is indeed B. Brilliant explanation provided by Eli Meyer, Kaplan GMAT instructor.
A is incorrect. In English, clauses (subject-verb structures) must be linked to one another by exactly one connecting phrase. In A, there is no connector between the clause "X-rays aren't needed" and "the OT rules were developed." It needs a "because," "since," or "so," to be correct; as written, it's a run-on sentence.
D is incorrect because the initial descriptive phrase, "developed to...", describes the OT rules, but the phrase is adjacent to "5% of patients." This is a modification error, and is incorrect.
E looks good; replacing a comma with a semicolon is one way to correct a run-on. However, the very last bit is garbled. 'when tested' is a descriptive phrase the needs to be followed by a comma, and "before the rules development" at the end of this version is a dangling modifier.
B and C are almost identical. Literally the only difference between the two is the order of the clauses. However, B has the superior order. B introduces "patients with foot pain" and "the OT rules" in it's first clause, then clearly refers back to "patients" and "the rules" in the second clause. C, on the other hand, starts by talking about the ambiguous "patients" and "the rules," and not until the second clause does it actually clarify the specifics of its subjects.
