Choose the correct Passive form of the sentence:

"This book will change your life".

Your life will be changed by this book.

Here's why:

• The original sentence is in the active voice, with "book" as the subject and "will change" as the verb.
• To convert it to the passive voice, we need to:
  • Change the subject ("this book") to the object ("your life").
  • Add the appropriate form of the auxiliary verb "be" ("will be") before the past participle of the main verb ("changed").
  • By the rule of "passive voice", we also need to add the preposition "by" and the agent of the action ("this book").

Therefore, the resulting sentence "Your life will be changed by this book" accurately reflects the passive voice of the original sentence.

The other options are incorrect:

• "You will change your life" is in the active voice and doesn't change the subject-object relationship.
• "Book would change you and life" is grammatically incorrect and doesn't accurately convey the original meaning.
• "Life is going to be changed via the book" is awkward and uses unnecessary words ("is going to" and "via").
