Detailed Solution & Explanation

**Concept:** SD measures spread/variability. With identical values, there is no variability. If profits are P\displaystyle P every month: - Mean = P\displaystyle P - All deviations = 0 - σ=0\displaystyle \sigma = 0 SD cannot be negative (it is always ≥0\displaystyle \geq 0), and in this case it equals exactly **Zero**. Hence, **Option C** is the correct answer.
