I gave my students this multiple choice question: More sulfur dioxide is being added to the atmosphere. How will this most likely affect the hydrosphere?

Only one answer is correct among these 4 choices:
- There will be a decrease in sea level.
- The acidity of the ocean will increase.
- There will be an increase in fresh water.
- The temperature of the oceans will decline.

Could you tell me which one is correct?

The acidity of the ocean will increase.
