Change to passive voice:
"She paints the wall."

• সঠিক উত্তর: ক) The wall is painted by her.

- মূল বাক্য: "She paints the wall." এটি একটি Present Indefinite Tense বা Simple Present tense-এর Active Voice sentence.
- Active Voice গঠনে "Subject + Verb (V1+s/es) + Object" ব্যবহৃত হয়েছে।
- Passive Voice গঠনের নিয়ম: Object + am/is/are + past participle (V3) + by + Subject.
- এখানে "the wall" হল object, এবং "paints" এর V3 হল "painted".
- তাই সঠিক passive form: "The wall is painted by her."

Other options:
খ) The wall was painted by her. → এটি Past Indefinite tense বোঝায়, ভুল।

গ) The wall has been painted by her. → এটি Present Perfect tense বোঝায়, ভুল।

ঘ) The wall will be painted by her. → এটি Future tense বোঝায়, ভুল।
