A long straight wire along the `z`- axis carries a current ` I` in the negative ` z- direction` . The magnetic vector field ` vec(B)` at a point having coordinates (x,y) in the ` Z = 0` plane is

A

`(mu_(0)l(yhati-xhatj))/(2pi(x^(2)+y^(2)))`

B

`(mu_(0)l(xhati+yhatj))/(2pi(x^(2)+y^(2)))`

C

`(mu_(0)l(xhatj-yhati))/(2pi(x^(2)+y^(2)))`

D

`(mu_(0)l(xhati-yhatj))/(2pi(x^(2)+y^(2)))`
