B. Assuming the wire is of a type of metal particular type. I believe the metal has to be of a metal that has certain properties. I am not sure of what those properties are.
Something to do with free electrons and such. Copper, makes a good sample of a metal that would successfully show a current flow as it moves through the magnetic field.

B)
You need movement either of the wire or of the magnetic field for current to flow.
