Cooking a cheeseburger physical or chemical

 Haha... I guess it depends on how well you cook. If you're a terrible cook and your food catches fire, thats chemical change. Because the compounds in whatever food you're cooking becomes oxidized by O2, meaning it changes to a new compound. 

If you're a decent cook and nothing catches fire, then it is only physical change, there are no reactions, just change of state.

Chemicle, once you cook it, the properties change plus youvcan never uncook it

B. would complete your answer. give me brainliest!
