Answer: খ) She said that she had lost her keys.

• মূল বাক্যটি Present Perfect Tense-এ আছে।

• Reported speech-এ tense পরিবর্তিত হয়ে Past Perfect হয়।

• have lost → had lost।

• বাক্যের অর্থ অপরিবর্তিত থাকে।

• সুতরাং সঠিক reported speech: She said that she had lost her keys.

Other options:

• ক) She said that she lost her keys. → have lost → lost নয়, had lost হওয়া উচিত।

• গ) She said that she has lost her keys. → Reporting verb past tense হলে, tense পরিবর্তন করা উচিত।

• ঘ) She said that she loses her keys. → Present Indefinite, অর্থ ও tense উভয়ই ভুল।

• এটি Third Conditional sentence। Conditional sentence-এ দুটি clause থাকে:

  1. If-clause (subordinate clause) – শর্ত বোঝায়

  2. Main/principal clause – ফলাফল বোঝায়

Third Conditional নিয়মাবলী:

• If-clause: had + past participle (V3)

• Main clause: would/could/might + have + past participle (V3)

• Negative: would/could/might + not + have + V3

• If-clause ছাড়া condition শুরু করতে চাইলে Had + subject + V3 ব্যবহার করা যায়।

Structure:

• If + Past Perfect (had + V3) + Subject + would/could/might + have + V3 + extension

উদাহরণ:

• If we had taken the train, we would have reached on time.

• If she had remembered the appointment, she wouldn’t have missed it.

• If you had called me, I could have helped you.

• If they had prepared better, the presentation would have been successful.
