Solution

The correct option is C Phylloclades
Both the main stem and the branches are modified into flat green organs performing the functions of leaves are known as phylloclade.

Only the stem branches are modified to take over the function of leaves in cladodes.

A phyllode is a modified petiole or a shoot that connects the stem with leaf; its function resembles that of a leaf.

A phylloclade is a flattened, photosynthetic branch or stem that resembles or performs the function of a leaf.

So, option C is correct.
