Correct Answer - D
The protoplasts carry negative charges on their surface and hence two protoplasts normally do not fuse when growing in culture medium. Its fusion is promoted by using electric shocks (electrofusion) or by using Poly Ethylene Glycol like chemical. They help in somatic hydridization and formation of cybrids, heterokaryocytes and synkaryocytes.
