Answer:
The evidence that best supports the student's reason is A. The results of a student survey suggest that twenty-three percent of the students consider themselves vegetarians.
Step-by-step explanation:
When writing an argumentative text, it is important to provide documentation, facts or information that indicate whether a statement or proposition is valid or true so as to support the argument of the text. This is called evidence.
Within these options, sentence A is the one that best supports the student's reason because it provides solid and objective data about the students diet, rather than mere opinion or any other piece of information that is not relevant to the claim or its reason.
