The correct option is C Strong nuclear force is very short ranged force
Well I have no other beautiful or organic way to present this to you.
So let me just state the facts that we know.
Strong nuclear force doesn't depend on the charge of nucleons. The magnitude of force between a pair of proton is same as a pair of neutron. Yeah it does depend on spin. And yes nucleons have spins just like electrons. Btw don't picture nucleon spin as a top or Shaktiman spinning.
Also nuclear force is very short ranged force, its range is a few Fermi’s, it asymptotes very fast, but in that range it’s the strongest force.
Just like humans can shoot a lion with a gun but, take that away and see the king of the jungle scare the shit out of them.
