Solution

The correct option is D $I - U; I I - P; I I I - S; I V - R$
I- Cathode rays are made up of electrons.
II- Alpha particles are made up of helium nuclei.
III- J.J. Thomson suggested that electrons are surrounded by a volume of positive charge. It looks like negatively charged "plums" embedded in a positively charged "pudding". So it is called as Plum Pudding model.
IV- X rays are part of electromagnetic radiation.
