Answer:
The correct answer would be D, The Aftermath.
Step-by-step explanation:
Accident chain is the series of events that occur from the start of the accident till the end of it. This series of event does not include the events afterwards. In this question, possible events that are included in the accident chain are given, and is asked to take out the event which would not be included in the accident chain. So there is a situation that creates the environment of accident, then there comes the accident itself, and then the treatment given immediately to the people on the spot of accident and in the hospital. But what happens after the treatment is not the part of the accident chain. So option D, the aftermath is not included in the accident chain.
