Select the option that expresses the given sentence in active voice.
The animals were frightened by the noise.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. The noise frightened the animals.
The given sentence is in passive voice: "The animals were frightened by the noise."
In active voice, the doer (the noise) becomes the subject performing the action.
Option 4 correctly uses the active form with plural subject and object matching the original meaning.
Option 1 changes the tense to past perfect, which is not the original tense.
Option 2 reverses the meaning incorrectly (animals frightening noise).
Option 3 has a singular object "animal" instead of plural "animals."
