Identify the correct active voice form.
Passive: “The work has been completed by the team.”

Correct option is B

The correct active form is option (b).

Correct Active Sentence:
• The team has completed the work.

Explanation:
• The given passive sentence is in present perfect tense: “has been completed”.
• To convert passive into active, the doer “the team” becomes the subject.
• The subject performs the action on the object “the work”.
• Therefore, the correct active structure is “The team has completed the work.”

Grammatical Rule Used (English):
• Passive: Object + has/have been + V3 + by + subject
• Active: Subject + has/have + V3 + object

Grammatical Rule Used (Hindi):
• Present perfect tense के passive voice में has/have been + verb की third form का प्रयोग होता है।
• इसे active voice में बदलते समय doer subject बनता है और संरचना has/have + verb की third form हो जाती है।

Explanation of Other Options:
• (a): This is simple past tense, not present perfect tense.
• (c): This is past perfect tense, which changes the original tense.
• (d): This is present continuous tense and is therefore incorrect.

So the correct answer is (b)
