Solution

The correct option is D Stem
Cladode is a stem modification where the stem is fleshy and green but has one or two nodes and internodes. Leaves are modified into scales, from the axil of which cladode arises. The presence of cladodes in unrelated desert angiosperm families is an excellent example of convergent evolution or the independent development of the same characteristic in unrelated taxa.
Thus, the correct answer is option D.
