Directions (1-6): In the following questions, a sentence is divided into four parts. Choose the part of the sentence which may contain a grammatical error in it. If all the parts of the sentence are grammatically correct and contextually meaningful, choose option “no error” as your answer choice.

In the bookstore, (A)/ she found a intriguing (B)/ novel that immediately (C)/ captured her attention. (D)

The correct answer is B.

Detailed Step-by-Step Explanation:
To identify the grammatical error, let us analyze each part of the sentence:

1. Part (A) "In the bookstore,": This is an introductory prepositional phrase establishing the setting. It is grammatically correct and punctuated properly with a comma.
2. Part (B) "she found a intriguing": This part contains a grammatical error. The indefinite article "a" is incorrectly used before the word "intriguing". The word "intriguing" begins with a vowel sound (/ɪ/). According to English grammar rules, the indefinite article "an" must be used before words that begin with a vowel sound. Therefore, "a intriguing" must be corrected to "an intriguing".
3. Part (C) "novel that immediately": This part is grammatically correct. The relative pronoun "that" is used correctly to initiate the relative clause modifying "novel", and the adverb "immediately" is placed correctly to modify the verb in the clause.
4. Part (D) "captured her attention.": This part is grammatically correct. The verb "captured" is in the simple past tense, which matches the tense of the main verb "found" (Part B), maintaining tense consistency throughout the sentence.

Thus, the grammatical error is in part B, and the corrected sentence is: "In the bookstore, she found an intriguing novel that immediately captured her attention."
