The parent function of the absolute value operator is given by the following function:
![y=|x|](https://img.qammunity.org/2023/formulas/mathematics/high-school/kh4fxxxmq7kz0zee8nw3v9dd6pk64iltp6.png)
In this function, the value of y is always greater than or equal to zero, since the absolute value operator always returns the number without a signal.
The graph of this parent function is:
Therefore the correct option is B.
