Match the items of List - I with those of List - II $\begin{array}{ll} \text{List - I (Complex number)} & \text{List - II (Polar form)} \\ \text{(i)} \sqrt{3}-i & \text{(a)} 2 \operatorname{cis} \frac{\pi}{6} \\ \text{(ii)} \sqrt{3}+i & \text{(b)} 2 \operatorname{cis} \frac{5 \pi}{6} \\ \text{(iii)} -\sqrt{3}+i & \text{(c)} 2 \operatorname{cis}\left(\frac{-5 \pi}{6}\right) \\ \text{(iv)} -\sqrt{3}-i & \text{(d)} 2 \operatorname{cis}\left(-\frac{\pi}{6}\right) \\ & \text{(e)} 2 \operatorname{cis} \frac{9 \pi}{6} \\ \end{array}$ The correct matching is
  1. $\begin{array}{cccc} \text { (i) } & \text { (ii) } & \text { (iii) } & \text { (iv) } \\ \text { d } & \text { b } & \text { a } & \text { e } \\ \end{array}$
  2. $\begin{array}{cccc} \text { (i) } & \text { (ii) } & \text { (iii) } & \text { (iv) } \\ \text { d } & \text { a } & \text { b } & \text { c } \\ \end{array}$
  3. $\begin{array}{cccc} \text { (i) } & \text { (ii) } & \text { (iii) } & \text { (iv) } \\ \text { b } & \text { d } & \text { a } & \text { c } \\ \end{array}$
  4. $\begin{array}{cccc} \text { (i) } & \text { (ii) } & \text { (iii) } & \text { (iv) } \\ \text { b } & \text { c } & \text { a } & \text { d } \end{array}$
