Correct option is A
The correct passive voice of the given sentence is
(a) A unanimous verdict has been delivered by the jury.
Explain the rules of conversion (Active → Passive) with structure:
·
Active tense: Present Perfect →
has/have + V³
·
Passive tense: Present Perfect Passive →
has/have + been + V³
·
Steps applied:
1. Object in active becomes subject in passive:
a unanimous verdict.
2. Keep the tense same:
has delivered → has been delivered.
3. Subject in active becomes agent with “by”:
by the jury (optional).
4.
Structure:
·
Active: Subject + has/have + V³ + Object
·
Passive: Object + has/have + been + V³ + (by + Subject)
·
Example:
The committee has approved the proposal. →
The proposal has been approved by the committee.
·
Why other options are incorrect:
·
(b) “was being delivered” = past continuous passive; tense changes incorrectly.
·
(c) “had been delivered” = past perfect passive; tense changes.
·
(d) “is delivered” = present simple passive; tense changes.
