Hi, let's start by recalling the argument. The author notes that some claim that people gesture less for abstract ideas than physical ones. They then tell us that while this correlation is not universal, that there are exceptions, the existence of these exceptions is not a good reason to reject the initial claim, since people think of things as abstract or physical in different ways.

In other words, the author is defending the scientists claim against an attack that the correlation is not universal by showing that the fact it is not universal is compatible with the initial claim.

This is a good match for c. The author is reconciling the initial claim with the apparently disconfirming evidence that it is not universal by appealing to the fact that people perceive concepts differently.
