Detailed Solution

The above statement is true.
The positive charge builds up on the upper portion of the clouds, and the negative charge on the lower portion. When the charge is accumulated in a large amount, the air present between the clouds breaks down and starts conducting electricity. This conductive air path creates a flash of light. Therefore, lightning is also an electric spark with a significant charge.
