Explanation:

To determine the correct treatment, we analyze each option:

• Option a (Gene therapy): By definition, gene therapy involves inserting genes into a person’s cells to treat or cure genetic disorders. This matches the description in the question.
• Option b (Chemotherapy): Chemotherapy is used to treat cancer by using drugs to kill cancer cells or stop their growth. It does not involve inserting genes to cure genetic disorders.
• Option c (Radiation): Radiation therapy (or radiation) is also used mainly for cancer treatment, using high - energy radiation to kill cancer cells. It has nothing to do with inserting genes for genetic disorder cure.
• Option d (Surgery): Surgery involves physical procedures like cutting, removing, or repairing tissues. It does not involve gene insertion for genetic disorder treatment.
