Select the correct active form.
"Why was the match postponed by the organizers?"

Correct option is C

The correct active/passive voice of the given sentence is (c).
Explanation: The original sentence is in the simple past passive: was + past participle (“was postponed”) with the agent “by the organizers.” To convert a Wh-question from past passive to past active, use Why + did + Subject + base verb + Object. Hence, “Why did the organizers postpone the match?” precisely mirrors the tense and meaning.
Grammatical rule used:
· Passive (Simple Past): Object + was/were + V3 (+ by + Agent)
· Active (Simple Past Question): Wh- + did + Subject + V1 + Object?
· Structure:
· Active voice: Subject + V2 (or did + V1 in questions) + Object
· Passive voice: Object + be (was/were) + V3 (+ by + Agent)
· Example: Why was the parcel delivered late by the courier? → Why did the courier deliver the parcel late?
· Info booster: In Wh-questions, keep the same tense after conversion: was/were (past passive) ↔ did + V1 (past active).
