What is spin in particle physics? Choose the most appropriate, precise definition provided.

• A trait of all subatomic particles

• The trajectory traced by leptons orbiting a nucleus or similar structure

• An intrinsic property of all subatomic particles that represents their angular momentum, as well as their symmetry

• An intrinsic property of all subatomic particles that determines how they interact with the strong and weak force, as well as the minimum degree of uncertainty in their position and velocity
