Consider A as below,

A={1,2,3}

A={1,2,3,4}

A={-1,0,1}

From the first 3 sets we can prove median is equal to mean.

From third set we can prove mean equal to zero

Mode means repeating integers that occurs mist frequently in the list.Since the set is consecutive integers,mode is not possible.

So option B is correct
