Answer:
The correct answer will be option- The indivisible part of the theory was discarded after the subatomic particles discovery because consensus of data must exist for theories to be valid.
Step-by-step explanation:
John Dalton is known for his atomic theory which states that matter is made up of indivisible atoms.
The subatomic particles of the atom were first discovered by J.J Thomson in 1897 when he discovered electrons, In 1920 Rutherford discovered protons and in 1932 James Chadwick discovered neutrons.
This led to a shift in the paradigm that atom is indestructible as new discoveries led to changes in the consensus data which opposed the atomic theory. This discarded the indivisible atomic theory.
Thus, the selected option is the correct answer.
