Answer:
The correct answer is A - a lightning bolt strikes a tall building.
An electrostatic discharge (ESD) is a sudden release of electric energy between two objects with different electrical potentials. Lightning is a massive ESD that occurs between a thundercloud and the ground or a building.
The other options are not examples of ESD:
B - A battery stopping producing electricity is an example of a battery running out of power, not an ESD.
C - An outdoor porch light being turned off is an example of switching off a device, not an ESD.
D - A match being struck against a rock is an example of a chemical reaction (combustion) and not an ESD.
