Answer:

The correct option is 3.

Explanation:

The summary of Dalton's atomic theory is listed below

1. All matter are made up of small indivisible substances called atoms (same as option 2)

2. Atoms of the same elements are alike in all aspect and are different from atoms of other elements (same as options 1 and 4)

3. Atoms combine in simple whole number ratio to form compounds

4. atoms can neither be created nor destroyed but it is the smallest unit of matter that can take part in a chemical reaction (this is contrary to option 3)

From the above, it can be deduced that "atoms change into other atoms in chemical reactions" is not part of Dalton's atomic theory.
