Explanation:

Electrostatic discharge is the sudden flow of electricity between two charged objects due to a build - up of static electricity. Lightning is caused by the build - up of static charge in clouds, and when a lightning bolt strikes a building, it is a large - scale electrostatic discharge. A battery stopping production is a chemical/energy depletion process, not electrostatic. Turning off a porch light is a circuit - based action, not electrostatic. Striking a match against a rock is a mechanical - chemical ignition process, not electrostatic.

Answer:

A. A lightning bolt strikes a tall building.
