Choose the option in which the above sentence has been changed into Passive Voice:
I expect to get a prize.

Correct option is B

Correct option (best passive among given choices): (b) A prize is expected by me
Explanation (highlight):
• Active meaning: “I” have an expectation about receiving a prize.
• Option (b) correctly brings object focus (“a prize”) and keeps present sense.
Grammatical Rule (English):
• Passive pattern: Object + is/are + V³ + by + Subject
व्याकरणिक नियम (Hindi):
• Passive में कर्म (object) पहले आता है और क्रिया be + V³ में बदलती है; “by” के बाद कर्ता आता है।
Why other options are incorrect:
• (a) “by him” → subject mismatch (me/him) + structure wrong.
• (c) awkward/incorrect structure; dummy “it” से अर्थ स्पष्ट नहीं बनता।
• (d) meaning changes: “expected of me” = दूसरों को मुझसे उम्मीद है (original meaning बदल गया)।
Hence, option (b) is the correct answer.
