Solution

The correct option is B Epinasty
Plants do not move and have been evolved for stationary mode of life. However plants show several types of movements. For example, opening of a flower bud is an example of increased growth of the upper surface of a plant part (such as a leaf- vegetative or reproductive/ floral), resulting in a downward bending of the part. This type of movement is called epinasty.
