If someone burns paper then pours water on it, is it a physical or chemical change?

its a chemical change

Explanation:

burning paper cannot be transformed back to paper, because it turned into ashes, therefore its a chemical change

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

option c is the correct answer.
