The sentence below is divided into four segments: (A), (B), (C), and (D). Identify the segment that contains a grammatical error. If the sentence is both grammatically and contextually correct, select “No error” as the correct answer.

The chief engineer (A)/ confirmed that the blueprints have (B)/ being verified meticulously by the technical committee (C)/ prior to beginning construction. (D)

The correct option is C.

Detailed Breakdown:
Let us analyze the segments of the given sentence:
• Segment (A): "The chief engineer" — The subject of the sentence, which is grammatically correct.
• Segment (B): "confirmed that the blueprints have" — The main verb and auxiliary verb introducing the subordinate clause.
• Segment (C): "being verified meticulously by the technical committee" — Contains the grammatical error. The auxiliary verb "have" must be followed by the past participle form "been" to form the present perfect passive voice ("have been verified"). The continuous participle "being" cannot be directly paired with "have".
• Segment (D): "prior to beginning construction." — Prepositional phrase functioning correctly.

Grammar Rule:
To form the perfect passive voice construction, the structure is:
Subject + has/have/had + been + Past Participle (V3)
Using "being" after "have" is grammatically incorrect in this context.

Corrected Sentence:
"The chief engineer confirmed that the blueprints have been verified meticulously by the technical committee prior to beginning construction."
