Select the correct active form of the given sentence:
"The assignment work has been successfully finished ahead of time by Pragna."

Correct option is D

The correct active voice of the given sentence is (d) Pragna has successfully finished her assignment work ahead of time.
Explain the rules of conversion in detail.
· Passive → Active: Object + has been + V³ + by Subject ⟶ Subject + has + V³ + object.
· Keep adverb placement: Adverbs like successfully typically appear between the auxiliary and main verb ( has successfully finished).
· Retain full content: Include “assignment work,” “ahead of time,” and subject Pragna.
Structure:
· Passive: Object (The assignment work) + has been + finished + (ahead of time) + by + Pragna
· Active: Pragna + has + finished + her assignment work + (successfully) + (ahead of time)
Why others are incorrect:
· (a) Missing the adverb successfully (loss of meaning emphasis).
· (b) Drops the word work (changes the NP).
· (c) have with singular subject Pragna is grammatically wrong; also correct placement of successfully is fine but verb agreement fails.
