Best answer
Correct answer is (b) Tesla

For explanation I would say: The SI unit of the magnetic field is tesla, named after the great scientist Nikola tesla. 1 tesla is 10^7 times the magnetic field produced by a conducting wire of length one metre and carrying a current of one ampere at a distance of one metre from it and perpendicular to it.
