• Correct Answer: D
• Desert xerophytes exhibit hard, waxy epicuticular leaves (cuticle) to reduce evaporation; tiny or absent leaves to minimize transpiration surface area; and thorns/spines (modified leaves) to reduce water loss and deter herbivores.
• All three are classic xerophytic adaptations to arid environments.
