Answer:
The correct option is D. Transfer useful genes from wild potato plants to the crop plants.
Step-by-step explanation:
Genetically engineered organism can be described as an organism that have a foreign gene inserted into their genome.
Genetically identical crops will be clones of each other,hence there will be no diversity. But instead of cloning, if the desired genes from a different plant possessing that characteristic are transferred to the other wild type crops then, the organisms will not be clones. They will be able to diversify as well as maintain the desired characteristics. Hence, statement D is the best possible solution.
