The correct answer is d. Pronuclear transfer is a type of in vitro fertilization technique that involves transferring the nucleus of a fertilized egg with healthy mitochondria from a donor egg to an egg from a woman with unhealthy mitochondria. This is done to prevent the transmission of mitochondrial diseases from the mother to her offspring.
