these are options
​

Answer 1

C. Spontaneous combustion

Answer 2

Explosion is occurring in this case.

• There are different types of combustion according to the type and amount of energy release.
• The combustion of the fire crackers is very similar to the characteristics of the explosion.
• Like the explosion, the combustion of the fire cracker creates a lot of heat and light energy. This extreme amount of heat generation forcefully breaks the hard shell of the firecracker and the bang like sound is created.
• That's why, we can easily say that the combustion of fire crackers is known as the explosion.
