The correct option is B Vitis and Passiflora
Stem tendrils are found in Vitis and Passiflora. Tendril is a modified stem or leaf found in some plants for support, attachments and sometimes for invasion. In plants like grapevine and pumpkins, stem tendrils develop from axillary buds for climbing. These are slender and spirally coiled structures. They do not have a lamina or blade but they can photosynthesize.
Thus, the correct answer is option C.
