The figure shows two different orientations of a proton in a magnetic field.Which orientation is at higher energy?
A)a
B)b
C)Both are at the same energy, and there is no other orientation at higher energy.
D)Both are at the same energy, but if the spin vector were perpendicular to the magnetic field the energy would be higher.
E)Both are at the same energy, but if the spin vector were perpendicular to the magnetic field the energy would be lower.

In orientation B, the proton's spin is directly opposed to the direction of the magnetic field, resulting in a higher energy state. In orientation A, the proton's spin is aligned with the direction of the magnetic field, resulting in a lower energy state. Therefore, orientation B is at a higher energy.
