Select the correct passive voice of the given sentence.
I have written a very strong letter to the local administration regarding the deteriorating law and order situation.

Correct option is C

The correct passive voice of the given sentence is (c).
Active Voice: Subject does the action (I have written…).
Passive Voice: Action is done to the subject (A letter has been written…).
Structure Conversion Rule:
· Active: Subject + has/have + V3 + Object
· Passive: Object + has/have + been + V3 + by + Subject
Example:
Active: She has finished the work.
Passive: The work has been finished by her.
Explanation:
The tense “have written” changes to “has been written,” keeping the perfect tense form in passive. The object “a very strong letter” becomes the subject.
Other Options:
· (a) Changes the subject incorrectly.
· (b) Incorrect doer and object.
· (d) “Was written” is past simple, not correct for present perfect.
