Somatic hybridization is achieved through

Explanation:

Somatic hybridization is a technique to achieve desirable individuals by hybridizing two parental somatic cells.

This is achieved by protoplast fusion.

The protoplast is fused with the help of polyethylene glycol where cells without the cell wall are fused to form dikaryon.

The nucleus is from both the parents and the cytoplasm is of the acceptor cell.

The resultants are known as somatic hybrids.

Final Answer:

The correct answer option is B, protoplast fusion.
