Select the most appropriate option that expresses the given sentence in active voice.
"The door was opened by Samira when the fire was reported by Mithali."

Converting Passive to Active Voice:
· Passive: "The door was opened by Samira when the fire was reported by Mithali."
· Active: "Samira opened the door when Mithali reported the fire."
Explanation:
1. Identify the subject, verb, and object:
· "The door" (object)
· "was opened by Samira" (passive) → becomes "Samira opened the door" (active).
· "The fire was reported by Mithali" → becomes "Mithali reported the fire."
2. Tense Consistency:
· Both actions happen in the past, so we keep the past simple tense: "opened" and "reported."
Other options:
· (a) "reports the fire" → Incorrect because the verb tense changes to present.
· (b) "was being reported by Mithali" → Incorrect as it introduces continuous tense unnecessarily.
· (c) "and Mithali reported the fire" → Incorrect because it changes the sentence structure and meaning.
Thus, the correct answer is (d) "Samira opened the door when Mithali reported the fire."
