The relative permeability is represented by mr and the susceptibility is denoted by c for a magnetic substance. Then for a paramagnetic substance [KCET (Engg./Med.) 2001]

• A.            mr < 1, c < 0                           
• B.            mr < 1, c > 0
• C.            mr > 1, c < 0                           
• D.            mr > 1, c > 0
