Best Answer

Answer: (b)

Solution : In grafting technique, two parts of two related plants are joined, so as to form a composite plant. In this, one plant called scion, having desired shoot is places on to a branch of related plant having strong root system, it is called stock. Grafted branch (scion) takes only nutrients and support to the stock plant and grows then flowering and fruiting. The quality of flowers and fruits of such a composite plant is mainly determined by scion itself.
