two infinite wires, carrying currents i1...

two infinite wires, carrying currents `i_1 and i_2`., are lying along x-and y-axes, as shown in the x-y plane. Then locus of B=0 is ,

A

locus of point where `B` is zero is a circle

B

locus of point where `B` is zero is a line

C

`B` decays hyperbolically along any line parallel to `x`-axis

D

`B` decays hyperbolically along any line parallel to `y`-axis
