The correct sequence of reagents which would convert p-Nitrotoluene to p-Iodobenzoic acid is

(i) $$\text{Br}_2 + \text{FeBr}_2$$, (ii) Mg in ether then $$\text{CO}_2$$, (iii) 3 $$\text{H}_2$$ and Pt or Ni catalyst, (iv) $$\text{HNO}_2$$ at $$0^\circ\text{C}$$, (v) KI solution

(i) $$\text{Br}_2$$ in $$\text{CCl}_4$$ and heat, (ii) NaI in acetone, (iii) 3 $$\text{H}_2$$ and Pt or Ni catalyst, (iv) $$\text{HNO}_2$$ at $$0^\circ\text{C}$$, (v) $$\text{H}_3\text{PO}_2$$

(i) 3 $$\text{H}_2$$ and Pt or Ni catalyst, (ii) $$\text{HNO}_2$$ at $$0^\circ\text{C}$$, (iii) $$\text{Cu}_2\text{Br}_2 + \text{HBr}$$, (iv) $$\text{KMnO}_4$$ and heat, (v) KI solution

(i) $$\text{KMnO}_4$$ and heat, (ii) 3 $$\text{H}_2$$ and Pt or Ni catalyst, (iii) $$\text{HNO}_2$$ at $$0^\circ\text{C}$$, (iv) KI solution
