Torques `tau_(1)` and `tau_(2)` are required for a magnetic needle to remain perpendicular to the magnetic fields at two different places. The magnetic field at those places are B1 and B2 respectively, then `(B_(1))/(B_(2))` is

A

`(tau_(1))/(tau_(2))`

B

`(tau_(2))/(tau_(1))`

C

`(tau_(1) + tau_(2))/(tau_(1) - tau_(2))`

D

`(tau_(1) - tau_(2))/(tau_(1) + tau_(2))`
