Answer:
The correct answer is A: "chocolate blueberry, and French vanilla" contains a punctuation error.
Step-by-step explanation:
The phrase "chocolate blueberry, and French vanilla" contains a clear punctuation error, in that it uses a comma before the word "and". That is, commas are used to separate within a sentence different concepts that have some kind of differentiation from each other, or to make a tacit enumeration, but the comma is used only up to the last option: in the last one, the word "and", thus giving knowledge that it is the last option or word of the enunciation. In the case, there is a punctuation error as both the comma and the word are used and in the last word of the options stated.
