The Correct Option is C
Solution and Explanation
The standard deviation of data is not affected by an additive constant. Adding a constant value to each observation in the dataset will shift the data, but the spread (and thus the standard deviation) remains unchanged. Therefore, the new standard deviation is still 6.
