Convert the sentence provided below from its passive voice structure to an active voice structure:
A letter is written to the editor by the citizen every week.

Correct option is B

The correct active/passive voice of the given sentence is (b).
Explain the rules of conversion (Passive → Active) with structure:
Passive voice (Simple Present):
· Structure: Object + is/am/are + V3 + by + Subject + time
· Sentence: A letter + is written + to the editor + by the citizen + every week.
Active voice (Simple Present):
· Structure: Subject + V1(s/es) + Object + place/time
· Sentence: The citizen + writes + a letter to the editor + every week.
Why option (b) is correct: It keeps the tense simple present, keeps the meaning same, and places the doer ( the citizen) as the subject.
Example:
Passive: A report is prepared by the clerk daily.
Active: The clerk prepares a report daily.
Explain why other options are incorrect:
· (a): Changes the doer; in passive, the doer is “the citizen,” not “the editor.”
· (c): Wrong tense (past) and also drops “to the editor.”
· (d): Changes tense/aspect to present perfect continuous and changes number (“letters”), so it is not an exact conversion.
