Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
For inadequately earthed signaling equipment, they do not provide safe and low resistance path for the atmospheric electricity to pass to the ground. SO the atmospheric charges reach the ground through that equipment itself, thus releasing sparks (electrical discharges).
