• Correct sentence: I asked Javed if he had passed.

- Interrogative sentence এর direct narration কে indirect narration এ পরিবর্তন করার সময় reported speech এর পূর্বে if বা whether বসে।

ক) I asked Javed had he passed.
- বাক্যটি ভুল।
- Because it lacks the conjunction "if" or "whether" to introduce the reported question. In English, when forming reported questions, the word order changes, and the subject follows the verb, but in this case, "had he passed" is in the wrong order.

খ) I asked Javed if he had passed
- বাক্যটি সঠিক।
- The conjunction "if" introduces the reported question, and the word order follows the correct structure for reported speech: subject + auxiliary verb + subject + main verb.

গ) I asked Javed if you had passed
- বাক্যটি ভুল।
- কারণ এখানে "he" এর জায়গায় "you" এর ব্যবহার হয়েছে। 
- বাক্যের subject এর সাথে pronoun এর মিল থাকতে হবে যা হলো "Javed."

ঘ) I asked Javed that had he passed
- বাক্যটি ভুল।
- Because it uses "that" instead of "if" to introduce the reported question. In reported speech, we typically use "if" or "whether" to introduce a reported question, not "that."
