Which statement best explains the movement of electric current from the clouds to the ground during a lightning storm? .

a. the ground and the clouds are both negatively charged.
b. the ground and the clouds are both positively charged
c. the ground is positively charged and the clouds are negatively charged
d. the ground is negatively charged and the clouds are neutral

Correct Answer is option C

Explanation:

Option A cannot be correct because if both earth and clouds are negatively charged then they will repel each other and electron cannot flow through it because electron is negatively charged and it will get attracted towards positively charged terminal. Hence electric current will not flow between them.

Option B

cannot be correct because if both earth and clouds are positively charged then they will repel each other and electron cannot flow through it.Hence electric current will not flow between them.

Option C

It is correct option because flow of current means flow of electron. so electron which are negatively charged particle will move from cloud to positively charged ground.

Option D

If clouds are neutral then electron will not be there and hence current will not flow.
