Answer:
Option C, nuclear model
Step-by-step explanation:
With the gold foil experiment, Rutherford discovered the following -
a) Most of the space with in the atom is empty
b) The center of the atom has a densely packed structure with a positive charge. This structure was named as nucleus and it was found that the positive charge of nucleus is due to the protons with in it.
