Median of u,-2u,-3u,-4u,-5u,-6u, and -7u is -4u
We can test any numbers
if u=-1/2 A is bigger, if u=2 B is bigger
We can test any numbers
if u=-1/2 A is bigger, if u=2 B is bigger

The answer must be D, it is true that the median is -4u so if we put u equall to -8 the result will be a positive number which is greater than A, and if we put u equal to a positive number then B is greater than A!!
