A.

Lithium (atomic number 3) has 3 protons and, as a neutral atom, 3 electrons; helium (atomic number 2) has 2 protons and 2 electrons. The common lithium isotope (Li-7) also has more neutrons (4) than the common helium isotope (He-4, with 2 neutrons), so lithium has more protons, neutrons, and electrons.
