Detailed Solution & Explanation

The standard deviation is a measure of dispersion that calculates how much the values in a dataset deviate from their arithmetic mean. If the profits of a company remain the same for the last ten months, it means all the ten observations are identical. Since there is no variation or dispersion in the data, the standard deviation is equal to 0\displaystyle 0. Hence, **Option C** is the correct answer.
