D Correct answer
Explanation

Grafting is a technique whereby tissues from one plant are placed or inserted into another in such a way that the vascular tissues of both the plants may join together. The plant which is selected for its roots is called as the stock and the one selected for its stems and leaves and flowers is called as the scion. For successful grafts, the events that should take place is the production of the callus tissue between the cells of the stock and scion. 

Thus, the correct answer is option D.
