As far as I can tell it would be D. I took 5 million and multiplied it by 8 to get that.
The farmers are seeing stronger bugs because not all bugs die to the amount of pesticide. Some areas are not spread evenly or some bugs are more resistant genetically.
C) is the best answer, because the stronger ones are reproducing in order to create new resistant bugs.

Answer:
A) Humans without this gene exhibit problem with oxygen binding in their red blood cells.
Explanation:
- Oxygen binds to red blood cells because of their hemoglobin component. It is a protein found in red blood cells.
- Each hemoglobin molecule is able to bind to four oxygen molecules.
- If the gene controlling hemoglobin production is absent in humans, the red blood cells will not be able to bind to oxygen.
- Hence, if the gene given in diagram is removed and it results in difficulty in binding of oxygen to red blood cells, that gene might be involved in hemoglobin production.
