B, because all the other are elements. You can tell because Carbon and Oxygen in CO are both capitals while something like Au is gold.
<span>Mass was not conserved during this change. When paper burns, oxygen from the air combines with carbon and hydrogen from the paper in a chemical reaction to produce CO2 and water vapour. These waft away after the burning, just like smoke. Therefore, the paper has a lighter mass, because some of the mass it held before (from the carbon and hydrogen) has been lost.</span>
The last option, "Energy that flows from a hot mug of tea to a cold hand." Hope this helps!
(This is because heat is the transfer of energy that you can well, feel. In simple terms. For this question and other like it you can do process of elimination because the only one that involves heat, is the last option.)
