Referring to the domain structure representation of ferromagnetic materials, what happens to the domains when an external magnetic field \( B_0 \) is applied as depicted in Figure 5.8?

1. A
   Domains disintegrate completely into random individual atoms.
2. B
   Domains orient themselves in the direction of \( B_0 \) and grow in size.
3. C
   Domains reverse their magnetic moments entirely opposite to \( B_0 \).
4. D
   Domains shrink to zero volume.
