During a simulated nanoscopic expedition through an isolated hydrogen atom, an automated probe attempts to track the valence electron by locking onto a single, continuous circular track. The vessel's quantum navigation system immediately aborts this mission protocol, replacing the deterministic flight path with a three-dimensional probability density cloud. Based on the quantum mechanical model of the atom, why is the autopilot's original tracking strategy fundamentally invalid?

A) Electrons accelerate continuously until nuclear gravity forces them into a rapidly decaying inward spiral.

B) Electrons do not follow predetermined trajectories, so their behavior is defined by spatial probability distributions called orbitals.

C) Nuclear repulsion confines moving electrons exclusively to discrete, flat polygonal pathways around the core.

D) Electrons remain entirely motionless at fixed nodal coordinates until perturbed by an external photon.
