Match the following $\textsf{IC}$ families with their basic circuits :

$\begin{array}{clcl} \text{a.} & \text{TTL} & \text{i.} & \text{NAND} \\  \text{b.} & \text{ECL} & \text{ii.} & \text{NOR} \\ \text{c.}  & \text{CMOS} & \text{iii.} & \text{Inverter} \\ \end{array}$

$\textbf{Code :}$

  1. $\text{a-i, b-ii, c-iii}$
  2. $\text{a-iii, b-ii, c-i}$
  3. $\text{a-ii, b-iii, c-i}$
  4. $\text{a-ii, b-i, c-iii}$
