In the picture below where should you cut and the stem of the rose plant to obtain a new plant?
D
The stem should be cut a little way below the node. Remember, that that vegetative propagation occurs from roots and shoots growing from the node of the plant. Without the node, a new plant will not grow. The cut should not be made at the node itself, because after burial, there is a chance that the node may get removed due to infection or scrubbing. So the correct answer is 'd'.
