Solution
The correct option is A Grape vine and pumpkin
Stem tendrils are aerial modifications of stem. They are formed when axillary bud modifies to form green, thread-like sensitive structures with adhesive glands for fixation. Also, they are found in plants with weak stems. For example, gourds (cucumber, watermelon, pumpkins) and grapevines.
Australian Acacia, Bougainvillea and strawberry have strong stems and hence, such plants do not require long slender and coiled stem tendrils.
