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 is the answer. If there is no error, the answer is 'D'. (Ignore the errors of punctuation, if any). (solve as per the direction given)

The sentence reads: "The warden forbade the student from leaving the hostel." Let's break it down to identify any grammatical error:

1. Option A - The warden:
   • This part is grammatically correct. "The warden" is the subject of the sentence, and there is no issue with this phrase.
2. Option B - forbade the student:
   • This part is also correct. The verb "forbade" is correctly used in the past tense, and it makes sense in the context of the sentence.
3. Option C - from leaving the hostel:
   • This part is correct as well. "Forbid" is typically followed by "from" when indicating the action being prohibited, and "leaving the hostel" is properly structured as the action being prohibited.
4. Option D - No error:
   • There is no grammatical error in any part of the sentence. All parts are correctly structured.
5. Final Answer:
   • The correct answer is D. No error.
