Question

a expanding gas drives the shot through the barrel.
b the firing pin strikes the primer.
c a spark ignites the gunpowder.
d gunpowder burns and converts to a gas.

Explanation:

When a shotgun trigger is pulled, the firing - pin first strikes the primer. This action initiates the ignition process. After the primer is struck, it creates a spark which ignites the gunpowder. The burning gunpowder then converts to gas, and the expanding gas drives the shot through the barrel. So the next event after pulling the trigger is the firing - pin striking the primer.

Answer:

B. The firing pin strikes the primer.
