For a normal distribution if the mean is M, mode is M₀ and median is M_d, then

• A

  $\mathrm{M}>{\mathrm{M}}_{\mathrm{d}}>{\mathrm{M}}_0$

• B

  $\mathrm{M}<{\mathrm{M}}_{\mathrm{d}}<{\mathrm{M}}_0$

• C

  $\mathrm{M}={\mathrm{M}}_{\mathrm{d}}{\mathrm{M}}_0$

• D

  $\mathrm{M}={\mathrm{M}}_{\mathrm{d}}={\mathrm{M}}_0$
