(i) Zero(0).      We know that reciprocal of A is \frac{1}{A}. So for 0, its reciprocal is not defined.

(ii) 1 and -1 .                                                    (Since  \frac{1}{1} = 1  and   \frac{1}{-1} = -1  )

(iii) Zero,0.                                                             (as -0=0)
