D) Sending low-frequency sound waves through the patient.

E) exposing the body to high levels of radiation.

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
