Answer

(c) Cathode rays have properties identical to particles.

Work Step by Step

Cathode rays are a stream of charged particles, usually electrons, that are emitted from the cathode (negative electrode) of a high-vacuum tube. Electrons are negatively charged particles with definite mass and momentum. They exhibit particle-like behavior, such as deflection by electric and magnetic fields, and can cause mechanical effects (e.g., turning a paddle wheel).
