Answer:

2) All four statements are part of Dalton's original atomic theory.

Explanation:

The postulates of the Dalton’s atomic theory are:

  • The atoms are indivisible which means that they can not be further divided.
  • Atoms of the matter can neither be created nor be destroyed in the chemical reaction.  
  • All atoms of the particular element are identical.
  • The atoms of the different elements vary in the size and the mass. and posses different properties.
  • The compounds are formed by the different whole number combinations of the atoms.
