Correct option is **(B) 3**

Mode - Mean = k (Median - Mean)

Mode = Mean + K.Median - K.Mean

Mode = K.Median + (1 - K)Mean

**We know formula**

Mode = 3 Median - 2 Mean

Keeping both equation equal

K.Meadian + (1 - K) Mean = 3 Median - 2 Mean

On Comparing coeficient

Median, K = 3

Mean, (1 - K) = -2

\(\therefore\)** K = 3**
