有没有小伙伴能用herl逻辑给这道题分个类？！

Scientistshave modified feed corn genetically, increasing its resistance to insect pests.Farmers who tried out the genetically modified corn last season applied lessinsecticide to their corn fields and still got yields comparable to those theywould have gotten with ordinary corn. Ordinary corn seed, however, costs less,and what these farmers saved on insecticide rarely exceeded their extra costs for seed.Therefore, for most feed-corn farmers, switching to genetically modified seedwould be unlikely to increase profits.  

Whichof the following would it be most useful to know in order to evaluate theargument?

(A)Whether there are insect pests that sometimes reduce feed-corn yields, butagainst which commonly used insecticides and the genetic modification areequally ineffective

(B)Whether the price that farmers receive for feed corn has remained steady overthe past few years

(C)Whether the insecticides typically used on feed corn tend to be more expensivethan insecticides typically used onother crops

(D) Whether most of the farmers who tried the genetically modifiedcorn last season applied more insecticide than was actually necessary

(E)Whether, for most farmers who plant feed corn, it is their most profitable crop

正确答案是D.

我的疑惑是，这道题属于herl逻辑分类里的统计枚举吗，farmers who use the genetically corn 属于样本，D中出现的是这个样本，而且也严谨，所以选择D？

求助各位！

属于因果关系推理：
前提：产量不变，非转基因种子更便宜，转基因种子节约的农药钱少于买种子的钱多花的钱
结论：转基因种子不能增加利润
BCE都是因果无关的，A选项sometimes太弱了，有的害虫不能代表一般情况。D选项，如果大多数人都在转基因种子上使用过多的农药，说明农药还可以节约更多钱，可以削弱结论。
