If I ______ a millionaire, I ______ helped every worthy cause. Fill in the blank with correct right form of verbs.

এটি একটি Third Conditional (Past Unreal Conditional) বাক্য - অতীতে যা ঘটেনি তার কল্পনা করা হচ্ছে।

সম্পূর্ণ বাক্য: If I had been a millionaire, I would have helped every worthy cause.

• 3rd Conditional এর নিয়মানুযায়ী,
- Conditional sentence এ Had + Sub + V3 + Extension এভাবে কোন sentence শুরু হলে সেটি Perfect conditional / 3rd conditional হয়।
- বা If clause- এ যদি (had + V3) হয়, তবে পরবর্তী clause a would/could/might + have + V3 + extension ব্যবহৃত হয়।
- যেমন: Had he listened to his coach, he would have won the match.

অন্য অপশনগুলো কেন ভুল:

ক) were, would
- "If I were a millionaire" → এটি Second Conditional।
- "I would helped every worthy cause" → ভুল, কারণ “would” এর সাথে helped নয়, শুধু help হবে।

খ) were, would have
- “If I were a millionaire” → Second Conditional
- “I would have helped” → Third Conditional (Past unreal)
- এখানে Second ও Third Conditional mix হচ্ছে, অর্থাৎ tense mismatch. তাই ভুল।

ঘ) have been, would have - "have been" ভুল; Third Conditional-এ "had been" লাগবে।
