Change the following sentence from Active Voice to Passive Voice.
A volley of stones hit the police force.

Correct option is D

Correct passive voice: (d) The police force was hit by a volley of stones.
Definition (Active Voice):
• Active Voice → The subject performs the action. (Hindi: कर्ता क्रिया करता है)
• Example: A volley of stones hit the police force.
Definition (Passive Voice):
• Passive Voice → The subject receives the action (object of active becomes subject). (Hindi: कर्म पर क्रिया होती है)
• Example: The police force was hit by a volley of stones.
Step-by-step conversion (in detail):
• Active sentence parts:
– Subject: A volley of stones
– Verb (Simple Past): hit (V²)
– Object: the police force
• Passive formation:
– Object becomes new subject: the police force
– Simple Past Passive structure: was/were + V³
– hit (V¹/V²/V³ is same) → hit (V³)
– Add agent using by: by a volley of stones
Grammatical rule (English):
• Active: S + V² + O
• Passive: O + was/were + V³ + by + S
व्याकरणिक नियम (Hindi):
• Simple Past passive: was/were + V³; object आगे आता है और कर्ता “by” से आता है।
Why other options are incorrect:
• (a) “is sure to be hit” → meaning changes; direct passive conversion नहीं।
• (b) यह active ही है (emphatic structure), passive नहीं।
• (c) “has been hit” → Present Perfect Passive; tense बदल गया।
Hence, option (d) is the correct answer.
