The right answer is B: It has 11 protons.

The number of protons contained in a nucleus (which is the atomic number) is characteristic of a chemical element. For a given atomic number, the number of neutrons defines different "types" of this element: isotopes. The variation of the number of protons of the nucleus of an atom, during a nuclear reaction, for example, causes a change in the element studied.
