.
In answer a,
, so it is a direct variation.
In answer c,
, so it is a direct variation.
In answer d,
, so it is a direct variation,
Only answer b is left, which means the answer must be 'b'.
We also know 'b' is the answer because it cannot be expressed as <span>. Instead, it is expressed as </span>
, which is not the same thing and is therefore not a direct variation.
Hope I helped, and let me know if you have any questions :)

#1 There is no area of a cube. There is only a volume.
#2 The formula is
where s is the side.
Substitute 729 in V since that is the volume.
Take the cube root and you will get 9.
So the formula is and the side is 9.
