Tendrils are an example of which plant modification?

Explanation:
Climbing plants use specialized organs formed from existing organs to gain support. Tendrils are slender, coiled structures that grasp onto supports to help the plant climb. In many climbers, these tendrils arise from the stem or a lateral stem branch, meaning they are stem tissue that has become a tendril. Because their origin is stem modification, they’re classified as a stem modification. This adaptation provides the necessary mechanical support for the plant to grow upward and access light. (Note: some species do use leaf-based tendrils, but the example here reflects stem-derived tendrils.)
