Solution
The correct option is C false, true (respectively)
We can say the burning of paper is a chemical change. In general all combustion processes are chemical changes.
Energy is either gained or lost by the reactants when a chemical change occurs. Thus chemical reactions are either endothermic or exothermic. Hence, option (D) F,T is the correct answer.
