The law of conservation of mass was first established by French Chemist Antoine Lavoisier.
It is stated that mass is is neither created or nor destroyed in any ordinary chemical reaction. Hence, the correct option is (d)

anonymous · Answer

Answer is C absolutely, law of conservation of mass is that mass is never created or destroyed. It can change form, solid, liquid, gas, heat, light. You just can't make things disappear completely, they can get smaller(have less mass) but that energy has been transformed into some other form, like heat, light or gas. http://en.wikipedia.org/wiki/Conservation_of_mass
