Solution

The correct options are
A A loud sound will be heard
B A bright light will be seen
During lightning, there will be an increase in temperature due, which causes an expansion of the air surrounding the cloud. The sudden expansion causes a pressure wave, which causes a loud sound.
Also, electrons lose energy and emit photons, which is visible in form of bright light.
