Insecticide Q is noteworthy both for its control of pests that attack crops and its benignity toward humans. However, its effects only last 30 days, a period insufficient to protect any major crop until harvest, and a reapplication of Insecticide Q usually kills the crop. Insecticide P, on the other hand, can be reapplied indefinitely without damaging the crop. Therefore, Insecticide Q has no discernible use in protection of major crops.
Which of the following, if true, most seriously undermines the argument?
A. There are several minor crops that can be harvested in as few as 20 days.
B. A third insecticide not mentioned in the passage protects crops better than either Insecticide Q or P.
C. Foods treated with Insecticide P are often banned from organic markets.
D. Both Insecticides Q and P can be used on the same crop.
E. The production of Insecticide P, once economical, has recently tripled in cost.

Please note -
A. Incorrect. Minor crops are not covered in the passage, hence out of scope.
B. Incorrect. Be that as it may, it is new information not directly contradicting anything in the passage.
C. Correct. As if foods treated with insecticide P are often banned in organic markets, and there are only two insecticides between P and Q, Q will at least be used, so it can be effective, even if only for 30 days.
D. Incorrect. Although it would not make Q useless, it doesn't necessarily make it useful.
E. Incorrect. Cost is not discussed in the passage, hence out of scope. It is unlikely that a change from USD 1 to USD 3 for insecticide costs would make a substantial impact.

here we are concerned with the choice that negates that Q has no discernible use in the protection of major crops??
A is about minor crops (so out of scope)
B is about characteristic of a third insecticide (so does nothing to negate the conclusion)
C discusses about often banning of P applicated foods from the market, (nothing to negate the conclusion)
D however states that both can be applied to the same crop, means that if first Q is applied followed by P, then Q cant be totally outvoted in the protection process (correct)
E talks about the cost increase of P (out of scope)
so D IMO
