Solution

The correct option is C Gold
  • Ernest Rutherford was a New Zealand-born British scientist, who won the Nobel Prize in Chemistry in 1908, for his work on nuclear physics, and for the theory of the structure of the atom.
  • In 1911, he performed the Alpha particle scattering experiment or the elastic scattering using a gold foil, which led to the birth of the nuclear model of an atom and was a major step towards how we see the atom today.
