Directions: Read each sentence to find out whether there is any grammatical error in it. The error, if any will be in one part of the sentence. The letter of that part will be the answer. If there is no error, mark (E) as the answer. (Ignore errors of punctuation, if any.)

After finding traces of poison (A) / in his dinner yesterday, (B) / Mohit accused his wife (C) / of trying to cause harm. (D) No error (E)

The sentence is grammatically correct as written. 'After finding traces of poison in his dinner yesterday' is a valid introductory phrase using the present participle 'finding'. The main clause 'Mohit accused his wife of trying to cause harm' follows correct structure with the verb 'accused' taking the preposition 'of', which is then followed by the gerund 'trying'. There are no errors in subject-verb agreement, preposition usage, or sentence structure.
