Athletics' governing body, the IAAF, last week cleared Ottey of accusations of steroid use and lifted a two-year ban after their arbitration panel said the IOC-accredited lab in Lausanne improperly tested Ottey's urine sample.
The IOC say it has no reason to question the accuracy of the reports.
This is unknown information given in the passage so it should be neither but the IA for some reason that I can't figure out marked it incorrect.
