By competing with rodents for seeds, black ants help control rodent populations that pose a public health risk. However, a very aggressive species of blank ant, the Loma ant, which has recently invaded a certain region, has a venomous sting that is often fatal to humans. Therefore, the planned introduction into that region of ant flies, which prey on Loma ants, would benefit public health.

Which of the following, if true, most strengthens the argument?

A. Ant flies do not attack black ants other than Loma ants.
B. Loma ants are less effective than many bird species in competing with rodents for seeds.
C. Certain other species of black ants are more effective than Loma ants in competing with rodents for seeds.
D. The sting of Loma ants can also be fatal to rodents.
E. The use of pesticides to control Loma ants could have harmful effects on the environment.

A is best. Since it doesn't attack other black ants other than loma ants, then there are still populations of blacks ants that keeps the rodent population in control.
