Matter cannot be created or destroyed.
This is the law of conservation of mass: in a chemical reaction atoms are rearranged into new molecules but the total number of each type of atom stays the same. The other statements are incorrect: the number of atoms is the same on both sides (so the second option is false), chemical reactions do not create new matter, and they do not reduce matter (they may release or absorb energy but mass/atoms are conserved).
