In the following question, 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 the answer choice. I had (A)/ finished my work (B)/ before he had arrived (C)/ at the station. (D)

Explanation

The error is in part (C) of the sentence. This sentence describes two actions that happened in the past, one occurring before the other. Grammatical Rule: When two actions occur in the past, the action that happened first is expressed in the Past Perfect Tense (had + V3), and the action that happened later is expressed in the Simple Past Tense (V2). In this sentence, finishing the work happened first (I had finished), and his arrival happened later. Therefore, 'had arrived' should be changed to 'arrived.' Correct Sentence: I had finished my work before he arrived at the station. So the correct answer is (c)
