Hi,
The correct answer is C.
Protons= 50 (because the atomic number of Sn is 50) —> The atomic number always represent the number of protons

Neutrons= 68 (if you want to find the number of neutrons, you need to do: atomic mass (118 in this case) - your number of protons (50)

Electrons= 46 (50 - 4)
