Step 1

Referring to the figure (c) given in the question, the base current is given as 20-microampere.

Now, applying the Kirchhoff’s voltage law to the output terminal:

Step 2

For the load condition, substituting the value of the collector current and the collector-emitter voltage equal to zero in equation 1, one by one as shown below:

Step 3

The load line characteristic is shown in figure b, for the base current of 20 micro-ampere.
