In the absence of skewness, the coefficient of skewness by Karl Pearson $$\left(S_{k}\right)$$, Bowley's $$\left(S_{q}\right)$$ and by Kelly's $$\left(S_{p}\right)$$ are:

A

$$S_{k} = 0; S_{q} > 0; S_{p} < 0$$

B

$$S_{k} = 0; S_{q} > 0; S_{p} > 0$$

C

$$S_{k} = 0; S_{q} < 0; S_{p} < 0$$

D

$$S_{k} = 0; S_{q} = 0; S_{p} = 0$$
