Solution

The correct option is A Gene therapy
Gene therapy is a treatment that consists of introducing into a patient a normal copy of one or more defective gene/s responsible for the patient’s disease. When a gene is damaged, the corresponding protein becomes abnormal or non-functional and it results in a diseases condition. The goal of gene therapy is to cure a genetic disease by repairing/replacing the damaged gene responsible for the disease.
