What is an accurate description of what occurs when a log burns

a. energy is created as the log burns b. the compounds that make up the log are converted into fire, heat, and energy. c. as the log burns, the nuclear binding energy of the molecules in the log is released. the nuclear binding energy is transformed into the light and heat of the fire. d. the molecules present in the log are transformed into molecules that contain less energy than the original molecules. the energy difference is the heat of the fire?Explanation:

conservation of mass

mass before something happens = mass afterwards
