"Stranded energy" in the context of electric vehicles (EVs) typically refers to the situation when there is stored energy in the battery that is not accessible or usable due to damage incurred during an accident. This could happen if the protective case or wiring harness is compromised, leaving the battery's energy unusable, even though it is still physically present in the battery.
So the correct option would be:
When there is stored energy in the battery after an accident that has caused damage to the protective case or wiring harness.
