The cold rolled grain oriented steel has ______ permeability in the direction of the grain orientation.

The other options are incorrect because:

• Option A is incorrect because cold rolled grain oriented steel has maximum permeability, not minimum permeability.
• Option C is incorrect because cold rolled grain oriented steel does have permeability, not nil permeability.
• Option D is incorrect because cold rolled grain oriented steel does have permeability in the direction of the grain orientation, not none of the above.
