The graph of $f(x) =[|x|]$ is the one in Option B. When $x=1.5$, the value of the function is $2$.
The graph of the greatest integer function $f(x)=[|x|]$ looks like a ladder with gaps on each 'step' (see page 253 of the textbook). Thus, its graph is the one in Option B. The graph shows that when $x=1.5$, the value of the function is $2$.
