A doctor who appears in commercials for a specific medicine wrote an article stating that many people could benefit from taking that medicine.

Explanation

Objectivity is strongest when a claim is supported by evidence and the source has little apparent conflict of interest. Choice B refers to multiple experiments and comes from a university research team, making it the best-supported and least commercially biased claim. The other claims come from people or organizations with a possible financial interest in the conclusion.
