Solution

The correct option is D Sexual separation of defectives
Sexual separation of defectives is the best method to prevent gene transfer to further generations. Defective genes present in parents will be transferred to further generation and thus the number of defective genes will increase in the gene pool. Isolating them sexually can prevent the occurrence of this major problem.
