Change the following from active to passive:
Will the authorities enforce the revised ordinance promptly?

Correct option is A

The correct passive voice of the given sentence is (a) Will the revised ordinance be enforced promptly by the authorities?
Explain the rules of conversion (Active → Passive) with structure:
Active structure: Will + Subject + V1 + Object + adverb
· Will + the authorities + enforce + the revised ordinance + promptly
· Passive structure: Will + Object + be + V3 + (by + Subject) + adverb
· Will + the revised ordinance + be enforced + by the authorities + promptly
· Example (rule used): Will the committee approve the proposal? → Will the proposal be approved by the committee?
· Why other options are incorrect:
· (b) being enforced is wrong after “will”; “will” requires be + V3, not “being.”
· (c) have been enforced changes tense to future perfect, which is not in the active sentence.
· (d) missing auxiliary be; passive cannot be formed without “be.”
