The sentence 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.

Years of misuse and lack (A)/ of repairs had slowly took (B)/ a toll on the ancient bridge, (C)/ leading to visible cracks and instability. (D)

The correct option is B.

Detailed Explanation:
Let us analyze the sentence structure and the verb tense used in segment (B):
The sentence utilizes the past perfect tense to describe an action that started and was completed in the past before another point in time. The past perfect tense is formed using the auxiliary verb "had" followed by the past participle (V3) form of the main verb.

Let's look at the conjugation of the verb "take":
- Present tense (V1): take
- Simple past tense (V2): took
- Past participle (V3): taken

In segment (B), the phrase "had slowly took" incorrectly uses the simple past form "took" instead of the past participle form "taken".
To correct the grammatical error, "took" must be replaced with "taken".

Corrected Sentence:
"Years of misuse and lack (A)/ of repairs had slowly taken (B)/ a toll on the ancient bridge, (C)/ leading to visible cracks and instability. (D)"
