Yes A is wrong...

few atoms hota hoga jisme nahi hota hoga... magnetuic moment cancel each other.. due to protons and electrons...

manipal, do protons hav magnetic moment?? A is true becoz all atoms r electrically neutral(it is quite absurd to this question). But i think diamagnetic atoms donnot hav magnetic moment.
But there the magnetic moments r there but they cancel out.
