Which lists the springs based on the amount of elastic potential energy from greatest to least

The elastic potential energy stored in the spring is

= (1/2) x (spring constant) x (distance stretched or compressed)²

If all four springs are stretched or compressed the SAME distance
from their equilibria, then the potential energy is just proportional
to the spring constant.

From greatest to least stored energy is exactly the same list as
from greatest to least spring constant:

X . . . . .  35
W . . . . . 24
Y . . . . . 22
Z . . . . .  15

  

When sunlight shines through an orange solution, the violet, blue and green wavelengths are absorbed. The other colors pass through.
