• A. Incorrect subject/verb agreement.
• B. Improper use of a comma.
• C. Incorrect use of a transitional phrase.
• D. Improper use of a semicolon.

Answer: (A)

The sentence contains a subject/verb agreement issue because the subject "buildings" is plural, while the verb "is" is singular. For the sentence to be grammatically correct, the verb should be "are" to match the plural subject. In English, verbs must agree in number with their subjects; therefore, when the subject is plural, the corresponding verb must also be plural. This ensures clarity in the sentence and maintains proper grammatical structure.
