Burning wood

D

Explanation:

burning wood

every other change is "reversable" or the object doesn't fundamentally change

the wood is still wood when you chop it, just in smaller pieces

the water is still H2O, just in a gaseous form

if you evaporate the water you can reclaim the sugar

once you burn the wood, it is no longer wood therefore it is a chemical change
