Solution

The correct option is C physical and chemical
Bursting of a balloon is a physical change since the kinetic energy of the particles of air inside increases the pressure on the inner walls of the balloon and it bursts. No new product is formed by bursting of balloon. While burning of fuel produces carbon dioxide and water as new products so it is termed as a chemical change.
