  1. He suggested that giving up smoking.
  2. He suggested that giving up smoking is done.

সঠিক উত্তর:
He suggested that smoking should be given up.
উত্তর
সঠিক উত্তর:
He suggested that smoking should be given up.
ব্যাখ্যা

The correct answer is - ঘ) He suggested that smoking should be given up.

advise/insist/propose/recommend/suggest+ gerund+ object যুক্ত Active voice কে passive করার ক্ষেত্রে,
​(1) প্রদত্ত Active voice এর Subject Verb বসে + (2) that বসে + (3) Gerund এর পরের object টি বসে + voice-এ রূপান্তরের নিয়মঃ। (4) should be বসে + (5) প্রদত্ত Gerund টি verb এ রূপান্তরিত হয়ে তার Past participle বসে। 
​Example:
​Active: He suggested giving up smoking. 
​Passive: He suggested that smoking should be given up.
​​
Other options
ক) He suggested giving up smoking. 
এটা Active voice-এ আগের মতই আছে, Passive নয়।

খ) He suggested that giving up smoking is done. 
“is done” → grammatically ভুল। Passive করার সময় “should be done” ব্যবহার করতে হয়।

গ) Smoking was suggested to be given up by him. 
সাধারণত “suggest” এর সাথে “to be done” ব্যবহার প্রচলিত নয়। 
তাই বাক্যটি সঠিক নয়।
