Answer:
D
Most states a have various levels of football competition in b their high schools so that schools with c similar numbers of students compete only against d them. e No error
Explanation:
The error in this sentence occurs at (D), where there is illogical pronoun use. It doesn’t make sense to say that schools competed against “them” when “them” could refer to “high schools,” “schools,” or even “students.” Instead, “one another” or “each other” is needed.
