↪  In our life time, I dont think so
↪  They will be making some robots but I think before any of this happens they will have to find a way to modify genes
↪  By modifying genes this could change people's hair and eye colour build etc
↪  This hasnt had any progress, but is sure to come in the future but I dont think unless there is a scientific revolution that humans will be engineered this way in our life span

Answer:
The correct answer is - option C.
Explanation:
The case in this the biological exterminators asks to use the biological concept which includes spraying the solution of the juvenile hormone to get rid of nymphs of specific insect and according to the assumption, this solution causes some alteration on the ability to reproduce of such nymphs and leads to only nonreproductive ones.

Thus, the correct answer would be - option C.
