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.

One of the student (A)/ delivered an insightful analysis (B)/ in class, showing a (C)/ strong grasp of the material. (D)

The correct option is A.

Step-by-step Explanation:

1. Identify the Grammatical Rule: The phrase "one of the" is always followed by a plural noun because it refers to a single individual or item chosen from a group consisting of multiple members.

2. Analyze Part (A): In part (A), the phrase "One of the student" uses the singular noun "student" instead of the plural form.

3. Apply the Correction: To make the sentence grammatically correct, "student" must be replaced with its plural form, "students".

4. Corrected Sentence: "One of the students (A) / delivered an insightful analysis (B) / in class, showing a (C) / strong grasp of the material. (D)"
