Change the voice-"They are serving the poor people"

Correct answer: The poor people are being served by them.

Present continuous tense এর ক্ষেত্রে Active voice থেকে Passive Voice করার নিয়ম:
- Active voice এর object টি Passive voice এ subject হিসেবে বসে।
- Subject অনুযায়ী is being/ are being বসে।
- মূল verb এর past participle form বসে।
- by বসে।
- Active voice এর subject টি Passive voice এ object হিসেবে বসে।

Other options:
খ) The poor people were being served by them.
- Present continuous tense হওয়ায় is being/ are being এর পর মূল verb এর past participle form বসে। তাই এটি সঠিক নয়।

গ) The poor people are been served by them.
- Present continuous tense এর passive Voice এর ক্ষেত্রে is being/ are being এর পর মূল verb এর past participle form বসে। এখানে "are been"এর ব্যবহার সঠিক নয়।

ঘ) The poor people were been served by them.
- Present continuous tense হওয়ায় is being/ are being এর পর মূল verb এর past participle form বসে। এখানে "were been"এর ব্যবহার সঠিক নয়।
