Error Spotting – Choose the segment (A–D) that contains a grammatical error; select “No error” only if the entire sentence is correct. Sentence: A) A detailed inquiry B) in the incident C) has been initiated D) by the Central Government.

Introduction / Context:This question probes correct prepositional collocation with “inquiry”. The standard expression is “an inquiry into something”, not “in the incident”.

Given Data / Assumptions:

• Noun: “inquiry”.
• Current preposition: “in”.
• Target collocation: “inquiry into the incident”.

Concept / Approach:Collocations are conventional pairings; using the wrong preposition can sound unidiomatic or wrong. “Into” expresses the idea of probing a matter, which matches “inquiry”.

Step-by-Step Solution:1) Identify the head noun and its prepositional complement.2) Replace “in” with “into”.3) Correct sentence: “A detailed inquiry into the incident has been initiated by the Central Government.”4) Therefore, B contains the error.

Verification / Alternative check:Check parallel collocations: “investigation into”, “probe into” — all take “into” for depth/entry into a topic.

Why Other Options Are Wrong:

• A, C, D: All parts are grammatically and stylistically fine.

Common Pitfalls:Overusing “in” after nouns of investigation.

Final Answer:Option B
