List I | List II |

(i) f is one-one and onto if (ii) f is one-one but not onto if (iii) f is onto but not one-one if (iv) f is neither one-one nor onto if |
(a) $A=R^{+}, B=R$ (b) $A=B=R$ (c) $A=R,B=R^{+}$ (d) $A=B=R^{=}$ |

The correct matching of list I to List II is

(i) (ii) (iii) (iv)

(1) (a) (b) (c) (d)

(2) (d) (b) (a) (c)

(3) (d) (a) (c) (b)

(4) (d) (b) (c) (a)
