Explanation:

Adding chemical compounds like nitrogen and phosphates indirectly causes global warming as it poisons marine life which kills them. However note that its indirectly causing global warming, not directly.

Humans creating acid rain will cause some wildlife to die but the effect is not direct as well. It requires a process to result in global warming which takes time.

Humans adding CO2 to the atmosphere is a direct cause of global warming as CO2 is a greenhouse gas that traps heat radiated from the sun, causing global temperatures to rise.

Chemicals creating a thicker ozone layer reduces global warming as ozone reflects radiation from the sun. Hence the option is scientifically wrong in this question.
