Answer 1

The correct option is A gene therapy

Gene therapy is a collection of methods that allow correction of a gene defect that has been diagnosed in a child/embryo. In this method, genes are inserted into a person's cells and tissues to treat a disease. Correction of a genetic defect involves delivery of a normal gene into the individual or embryo to take over the function of and compensate for the non-functional gene.

So, the correct option is 'gene therapy'.
