The original sentence is in the active voice: “She took the dog for a walk.”
To change this into passive voice, we need to make the object (“the dog”) the subject of the sentence.
In passive voice, the structure is: Object + was/were + past participle + by + subject.
So, “The dog” becomes the subject, and “took” becomes “was taken,” while “she” becomes “by her.”
Thus, the correct passive form is: “The dog was taken for a walk by her.”
Let’s check the other options:
- (B) The dog took her for a walk — This changes the meaning and voice; it's active and incorrect.
- (C) The dog was took for a walk — Grammatically incorrect. “Was took” is wrong; it should be “was taken.”
- (D) The dog took a walk by her — Also incorrect in meaning and structure.
Hence, the only correct passive voice conversion is (A) The dog was taken for a walk by her.
