I wish I had seen you before. (Exclamatory)
Wow! I seen you before.
Had I seen you before!
Correct
Oh! I seen you before.
If I seen you before
Explanation:
Correct Answer is: Had I seen you before!
• I wish I had seen you before এর সঠিক exclamatory sentence টি হবে – Had I seen you before!
• I wish থাকলে এর পরিবর্তে had, could, if, would দ্বারা বাক্য শুরু হয়।
– বাকি অপশনগুলোর grammatical structure ভুল আছে এবং এদের অর্থেরও পরিবর্তন ঘটেছে।
