Answer
B. Rutherford
Explanation
The discovery of the proton is attributed to Ernest Rutherford. In 1917, Rutherford conducted experiments where he bombarded nitrogen gas with alpha particles, which led to the observation of hydrogen nuclei (protons). This experiment provided evidence for the existence of the proton as a fundamental particle in the nucleus of an atom.
