Choose the option in which the given sentence has been changed into passive voice.
I wrote this book.

Correct option is C

The correct active/passive voice of the given sentence is (c).
Explain the rules of conversion (Active → Passive) with structure.
· Simple Past Active: Subject + V2 + Object → “I wrote this book.”
· Simple Past Passive: Object + was/were + V3 (+ by + agent) → “This book was written by me.”
· Here “wrote” (V2) converts to “ was written” (was + V3). The object “this book” becomes the subject in the passive; the subject “I” becomes the agent “by me.”
· Structure:
· Active: I (S) + wrote (V2) + this book (O)
· Passive: This book (S) + was written (was + V3) + by me (Agent)
· Why other options are incorrect:
· (a) had been written = Past Perfect Passive, not Simple Past.
· (b) has been written = Present Perfect Passive, wrong tense.
· (d) is being written = Present Continuous Passive, wrong tense.
