Match the complex ions given in Column I with the hybridisation and number of unpaired electrons given in Column II and assign the correct code :

**Column I (Complex ion)** | **Column II (Hybridisation, number of unpaired electrons)** |

A. [Cr(H_{2}O)_{6}]^{3+} | 1. dsp^{2}, 1 |

B. [Co(CN)_{4}]^{2–} | 2. sp^{3}d^{2}, 5 |

C. [Ni(NH_{3})_{6}]^{2+} | 3. d^{2}sp^{3}, 3 |

D. [MnF_{6}]^{4–} | 4. sp^{3}, 4 |

| 5. sp^{3}d^{2}, 2 |

**Code :**

(i) A (3) B (1) C (5) D (2)

(ii) A (4) B (3) C (2) D (1)

(iii) A (3) B (2) C (4) D (1)

(iv) A (4) B (1) C (2) D (3
