Solution

The correct option is A Spine like leaves
The leaves of desert plants are modified to spines. This reduces the surface area and in turn, reduces the loss of water by transpiration. Spines also protect the desert plants from being eaten by animals. Their stem is usually green and fleshy. It performs photosynthesis and also stores water.
