The correct option is A Parasexual/somatic hybridisation
Protoplast fusion is a technique to get hybrid plants with desired characters. The protoplast obtained from the parent plants are fused together to form a hybrid cell which is cultured on nutrient media. The cell produced by the protoplast fusion is known as a hybrid which causes some variations in characters due to change in the genetic pool. This variation is known as somatic hybridization because it takes place in somatic cells. So, the correct answer is option A.
