| The field of a hollow wire with constant current is homogenous. Curves in the graph shown give, as functions of radius distance r, the magnitude B of the magnetic field inside and outside four long wires a, b, c and d carrying currents that are uniformly distributed across the cross-sections of the wires. Overlapping portions of the plots are indicated by double labels. |

| Read the given passage carefully and give answer of the following questions: |
A) a
B) b
C) c
D) d
Correct Answer: A
