A current I is flowing through a loop. The direction of the current and the shape of the loop are as shown in the figure. The magnetic field at the centre of the loop is `(mu_(0)I)/(R)"times" ("Here, MA=R MB=2R", angleDMA=90^(@))`

A

`(5)/(16)(mu_(0)i)/(R )`, but out of the plane of the paper

B

`(5)/(16)(mu_(0)i)/(R )`, but into the plane of the paper

C

`(7)/(16)(mu_(o)i)/(R )`, but out of the plane of the paper

D

`(7)/(16)(mu_(o)i)/(R )`, but into the plane of the paper
