Which choice gives the best summary of the idea in the selection?

• Some animals, such as jellyfist, can produce their own light. By transferring the light-producing gene to dogs, scientists have found a way to make dogs glow when placed under ultraviolet light. This could lead to important discoveries.

• The fascinating study of bioluminescent sea creatures has led to new research for curing diseases. However, scientists now cruelly perform tests, such as gene transfers, on live animals.

• By sucessfully transferring genes from light-producing sea creatures to dogs, scientists have found a way to study and possibly cure dieseases in people. Although there are several drawbacks, scientists are hopeful that the challenges can be overcome."

• Scientists have discovered a cure for Alzheimer's disease. By tranferring genes from bioluminescent sea creatures to dogs, researches discovered where disease-producing genes can be found. They found ways to prevent these genes from becoming active.
