The following columns present various modes of induction machine operation and the ranges of slip

$$\begin{array}{ll} \qquad \qquad\textbf{A} & \qquad  \textbf{B} \\ \quad \underline{\text{Mode of operation}} & \quad \underline{\text{Range of Slip}} \\ \text{a. Running in generator mode} & \text{p) From 0.0 to 1.0} \\ \text{b. Running in motor mode} & \text{q) From 1.0 to 2.0} \\ \text{c. Plugging in motor mode} &   \text{r) From -1.0 to 0.0}  \end{array}$$

The correct matching between the elements in column $\mathbf{A}$ with those of column $\mathbf{B}$ is

  1. $a-r, b-p$, and $c-q$
  2. $a-r, b-q$, and $c-p$
  3. $a-p, b-r$, and $c-q$
  4. $a-q, b-p$, and $c-r$
