Step-by-step explanation:
Given

Required
The graph of the step function
Before plotting the graph, it should be noted that:
and
use closed circle at its end
and
use open circle at its end
So, we have:

The line stops at -1 with an open circle

The line starts at - 1 and stops at -1 with a closed circle at both ends

The line starts at 1 with an open circle
The options are not complete, so I will plot the graph myself.
