This one took a few reads over, but I think that the evidence in the experiment only shows that oscillation occurred, not that they have mass. That is, it proved that oscillation, which shows that they do have mass, occurs. This in turns shows that they do have mass, but it needs the intermediate step of showing the oscillation occurred.Emil-Kunkin on August 5, 2023
I think a is wrong because it's missing the part about neutrinos which is important, and a major part of the passage.
