Answer is Right!
Answer is Wrong!
The correct answer is: D. No error
The sentence is grammatically correct. The subject and verb agree, and the tense is consistent. The preposition “at” is used correctly to indicate the location of the information.
The other options are incorrect because they contain grammatical errors. Option A is incorrect because the verb “are” does not agree with the subject “number.” Option B is incorrect because the preposition “indicated” is used incorrectly. Option C is incorrect because the sentence is incomplete.
