Let f : {x, y, z} → {a, b, c} be a one-one function and only one of the conditions (i) f (x) ≠ b, (ii) f (y), = b
(iii) f (z) ≠ a is true then the function f is given by the set
  1. {(x, a), (y, b), (z, c)}
  2. {(x, a), (y, c), (z, b)}
  3. {(x, b), (y, a), (z, c)}
  4. {(x, c), (y, b), (z, a)}

Answer

(C) (x, b), (y, a), (z, c)
