Solution
The correct option is C Alpha particles emitted by radioactive elements are used Alpha particles are nothing but helium nucleus.
When electrons are removed from a helium atom, only two protons are left in its nucleus which makes it positively charged. The alpha particles emmited from radioactive elements are used in Rutherford's experiment.
