Select the option that expresses the given sentence in active voice.

The jewel thief was punished by the judge.

The judge punished the jewel thief.

The correct active form of the given sentence "The jewel thief was punished by the judge" is The judge punished the jewel thief.

The passive voice of the sentence is "The jewel thief was punished by the judge." This sentence is in the simple past tense, which is used to describe an action that happened in the past. The passive voice of the sentence is formed by putting the subject of the active sentence after the verb "to be" and the past participle of the main verb. In this case, the subject of the active sentence is "jewel thief" and the main verb is "punish." The past participle of "punish" is "punished." So, the passive form of the sentence is "The jewel thief was punished by the judge."

The active voice of the sentence is formed by putting the subject of the passive sentence before the verb and removing the word "by." In this case, the subject of the passive sentence is "judge," and the verb is "punish." So, the active form of the sentence is "The judge punished the jewel thief."

The other options are incorrect because:

• Punishment had been given to jewel thief." This sentence is in the past perfect tense, which is used to describe an action that happened in the past before another action happened. However, there is no other action mentioned in the sentence.
• The police had punished the jewel thief." This sentence is in the past perfect tense, but the subject of the sentence is incorrect. The subject of the sentence should be "judge."
• Punishment was given to jewel thief." This sentence is in the simple past tense, but the subject of the sentence is incorrect. The subject of the sentence should be "judge."
