Answer
Assertion is true but reason is false
Explanation
Lightning indeed represents a large-scale electrostatic discharge, so the Assertion is correct.
However, it is produced by the build-up of opposite charges—typically negative charges in the lower part of a cloud and positive charges on Earth’s surface or in another cloud—not by the build-up of like charges. Therefore the Reason is incorrect.
