Explanation:

The error in the original sentence is the use of "affect" as a noun instead of "effect". "Affect" is usually a verb, while "effect" is the correct noun form here. Also, "childrens" is an incorrect plural form of "child"; the correct plural is "children". The subject - verb agreement in "research shows" is correct as "research" is a singular noun.

Answer:

A. Cell phones shouldn't be allowed in an educational setting because research shows they have a negative effect on children.
