Match the items given in List $A$ with those of the items of List $B$:
$A$. $|x| + |x - 2|$$I$. Right hand limit does not exist at $x = 2$.
$B$. $\text{cosech } x$$II$. Continuous only for non-zero real values of $x$.
$C$. $x - [x]$$III$. Limit is zero for all real $x$.

$V$. Discontinuous at all integral values of $x$.

The correct match is:

Find all points of discontinuity of $f,$ where $f$ is defined by
