The correct option is A Xerophytes
Cladodes (cladophylls) are green stems of limited growth (usually one internode long) which have taken over the function of photosynthesis from the leaves. The true leaves are reduced to scales or spines. Like phylloclades, cladodes are an aerial modification of the stem to reduce transpiration in xerophytic plants. Cladode may be made up of only internode, e.g., Asparagus or two internodes, e.g., Ruscus.
