Correct Answer: Electron
Solution : The correct answer is electron.
In Quantum Mechanics, dual nature of a particle theory was given de Broglie in 1924. He said that when a particle is moving it exhibits both the particle nature and the wave nature. Electrons also exhibit the property of both particle and wave when it moves. The Davisson and Germer experiment, in which they diffracted an electron beam of light verified the dual nature of electron.
