C; A singleton set
Step-by-step explanation:
Mathematically, when a number is non-negative; it is either positive or zero
Now, this is because 0 identifies as neither a positive or a negative number

What this mean is that we are having a set with a single number result
So we have our answer as {0}
Which is a singleton set
