(A) Onion
(B) Sorghum
(C) Maize
(D) Soyabean

Answer 1

Hint: Transplantation is the technique of moving a plant from one location to another. In transplantation seedling, the seedlings are transferred from one location to another.

Complete answer:
Transplantation seedling involves following procedure:
Seeds are grown in the soil. Proper nutrients and water are added in the soil for proper growth and development of seed into seedlings.
The seedlings are taken from the soil. Then they are grown in another land for their further maturation. The nutrients and water are given to the seedling for their proper growth and development.
Onion crop is grown in India by transplantation seedling technique. Seeds are grown in the soil. Then they are grown for their further development into seedlings. Proper care is used for selecting the seedlings. Over aged and under aged seedlings are avoided for transplantation. Because there are not found proper growth in case of over aged and under aged seedlings. Top third part of the seedlings are cut for good establishment. Optimum spacing between plants is 10 cm whereas optimum spacing between rows is 15 cm.
Sorghum, maize and soybean crops are not cultivated by transplantation techniques. Seeds are grown directly in the soil. Then they are not transplanted to another land. They are allowed to grow in the same land up to their maturation stage.

That's why the correct answer is "onion".

Note: Transferring of one stage of plant cycle is done to another land by means of transplantation technique.
