Select the option that expresses the given sentence in active voice.
Stones were thrown at the dog.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. They threw stones at the dog.
The original sentence is in passive voice and simple past tense: “Stones were thrown at the dog.”
To convert it into active voice, the subject performing the action (they) should be placed at the beginning, and the verb should be in simple past tense.
Option 4 correctly changes it to active voice in simple past tense.
Options 1 and 3 use past perfect continuous and past continuous tenses, which do not match the original tense.
Option 2 is present tense, which is incorrect for the given sentence.
