Solution

The correct option is C Polyethylene glycol
Somatic fusion, also called as protoplast fusion, is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both, a somatic hybrid. In this process, protoplasts from different plants are fused in the presence of polyethylene glycol, a cell agglutinator to form somatic hybrid cells. The effects of PEG are not specific and it will promote the aggregation and fusion of protoplasts from the same or different species.
