The correct answer is C. The critic said that there was nothing special about the movie; it was in every way unexceptional.
Step-by-step explanation:
According to the entry, the meaning of the word unexceptional is "ordinary" this means something or someone unexceptional is common or usual. This meaning is only shown in the sentence "The critic said that there was nothing special about the movie; it was in every way unexceptional" because if the critic considers the movie has nothing special this movie can be described as common, ordinary, or unexceptional, which means the word unexceptional reflects its correct meaning.
On the other hand sentences such as "The principal's unusually high standards for student behavior were considered unexceptional" reflect the meaning of the word unexceptionable because, in this case, the standards of the principle are not ordinary but they are beyond objection or cannot be criticized.
