Answer:
A. The population of grasshoppers will be able to be sprayed with the pesticide and remain unaffected.
Explanation:
As mentioned in the question statement, scientist inserted a gene in a grasshopper population that encodes for immunity against a pesticide. Therefore, the grasshopper population would be able to survive well despite the pesticide is being sprayed. Principally, pesticide spray can kill the invertebrates such as grasshoppers. However, when the grasshopper has a gene that encodes for a protein that gives immunity against the pesticide, the effect of spray will be minimized. They will produce the immunity protein and this protein will help them survive in toxic conditions.
