Answer:
The correct option is D) They can insert the gene for the protein from plant species Bigous moldkillae into a chromosome in Yummious letus.
Step-by-step explanation:
Biotechnology can be described as the technology in which the genome of organisms are altered so that organisms with better qualities can be produced. In the scenario discussed in the question, techniques of biotechnology can be used to insert the fungus-killing gene of Bigous moldkillae into the genome of the Yunnious letus. In this way, the Yunnious letus species will become resistant to the fungal infections.
