Hi.
Recently I'm dealing with SAT, and I found this sentence quite normal but the answer said no:
As their brains mature neurologically, infants become more capable to distinguish the shapes and textures of the objects around them.
Underlined portions are portions possibly wrong, and there would be only one error at most.
Originally I thought perhaps the last one was considered wrong but the answer told me that it was choice C, to distingush that was wrong.
I checked Merriam-Webster, but it appeared that such usage is right so I'm confused.
Is it possibly a diction error that "distinguish" need to be replaced by another word?

    of distinguishing


    To further clarify, "As their brains mature" tells us this is an ongoing process, so we use the present participle.
