Answer 1

Answer: (D)

Scion is a type of vegetative propagation. The process of artificially growing the plants is known as vegetative propagation. Artificial vegetative propagation is usually used for propagation or reproduction of those plants which produce either very few seeds or do not produce viable seeds. Some the examples are Banana, pineapple, artificial rose, orange, grape etc. Layering, grafting, cuttings and tissue culture are some types of artificial propagation. Scion or grafting of a plant means removing the twig or viable bud from the plant and inserting or tying it to the other buds especially the aerial part/stem(Stock) of the other plant. The stock provides the nutritional support to the stock of the plant.

So, the correct option is 'Grafting'.
