What is more serious: flashback or backfire?

Flashback
Backfire
They are equally serious
Neither is serious

The correct answer is: Flashback

While both flashback and backfire can present serious risks and consequences, flashback is generally considered more serious due to its potential to ignite a fire or explosion. Backfire, on the other hand, is typically a contained explosion that occurs in the engine of a vehicle, causing disruption but not necessarily posing a direct danger to individuals. Choice C is incorrect because while both can have serious effects, the level of danger is not necessarily equal. Choice D is also incorrect as both flashback and backfire can have serious consequences and should not be dismissed as not serious.
