Solution

The correct option is A

Attract the positive charges to the surface, and cause them to accumulate


When lightning strikes the Earth, it is because there is a build-up of negative charges at the bottom of the cloud and positive charges at the ground surface. This is charging by induction. The negative charges attract the opposite (positive) charges towards them.
