Using armored vehicles to detonate buried land mines entails an unavoidable risk of injury or fatality, but disarming and removing land mines manually currently entails an even greater such risk to those who remove land mines per mine removed. Therefore, in order to reduce the risk of injury or fatality without decelerating the effort to remove buried land mines, we must increase the use of armored vehicles and disarm fewer land mines by hand.
Which of the following, if true, most seriously undermines the argument above?
A. Manual mine disarmers can be quickly trained in methods that significantly decrease their risk of injury or fatality.
B. Injuries caused by manual disarmament tend to be far more serious than injuries caused by armored vehicle detonations.
C. The delivery of armored vehicles with which to detonate buried land mines can be organized easily by military field operatives.
D. Land mines detonated by armored vehicles destabilize the land surrounding the mine, while land mines that are successfully disarmed manually cause no such damage.
E. Hiring and training those who remove mines by hand is far less costly than is importing heavy armored vehicles to detonate buried land mines.

B and C tell us why armored vehicles are a good option, so they don't undermine the argument. E tells us vehicles are expensive, but the argument has nothing to do with expense; we only care which method will "reduce the risk of injury or fatality".
That leaves A and D. Answer D tells us vehicles "destabilize the land". What does that mean? Does that increase "risk of injury or fatality"? I have no idea. So there's no way to tell if D is a good answer. But there's also no way to tell if A is a good answer. For A to be right, we need to assume this training "that significantly decrease their risk of injury" is training that manual mine disarmers are not currently getting. There's no way to tell from the wording of the stem if the manual disarmers are trained, and still have a higher risk of injury than vehicle operators, or if they're untrained, and the training might reduce their risk of injury to such a degree that manual disarmament becomes safer than vehicle disarmament.
I'd imagine that A is the "OA", but as with many prep company Verbal questions, it's really just a guessing game trying to figure out which answer is correct.

Confused between A and D.
THe argument in the question compares the rates of injuries in between manual detonation and detonation using armoured vehicle. But in D, it just mentions and compares a type of injury, it doesn't address the main issue---which option has less chance of injuries overall.
