Answer:
C. All of the data values are identical.
Step-by-step explanation:
If the standard deviation for a set of data is 0, then all of the data values are identical.
When a standard deviation is 0, then the variance is also 0 and the mean of the deviation that is squared is also 0, thereby making all the values identical to the mean, that is 0.
