It's D, spine in plants. Water conservation in plants is mostly seen in succulent leaves, stems, and roots, not spines. Plants with spines don't usually have them for water conservation. The other options are adaptations that help plants to conserve water. Scales on fish, succulent stems, and thick leaves all help to reduce the amount of water that's lost through the surface of the plant. So spines are not used for water conservation, and are the exception in this list.
