The last option is the correct answer. Thomson's results from experimenting with cathode rays provided the first experimental evidence that atoms were made up of smaller particles. This discovery challenged the prevailing idea of the time that atoms were indivisible and led to the development of the atomic theory and the understanding that atoms are composed of smaller subatomic particles.
