Solution

The correct option is A
Protoplast fusion

When a hybrid is produced by the fusion of somatic cells of two species, it is known as a somatic hybrid, and the process of producing somatic hybrids is called somatic hybridisation. This is achieved by protoplast fusion which involves the fusion of protoplasts in a polyethylene glycol (PEG) or sodium nitrate solution.
