Solution
The correct option is C Needle like leaves
The leaves of desert plants are modified to spines, which reduce the surface area hence reducing the loss of water by transpiration. The stem is usually green and bulbous. The stem performs photosynthesis and also stores water. The spines also prevent animals from eating the plant.
