請教一下這一題答案選什麼好

大牛們好像都是選B

可是我覺得好像C and D都很不錯

可以幫忙一下嗎 感謝!

1.        一
        道GWD的變體，A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants.  Agronomists studying the herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert.  Possibly, therefore, the herb’s high histidine production is what allows it to grow in metal-rich soils

原題問support,現在問evaluate這個結論，給了5個whether，我看了下原題，基本上就是原來的選項加上個whether

原GWD 選項

a hypothesis that would gain support if ______.       

A: histidine is found in all parts of the plant – roots, stem, leaves, and flowers

B: the herb’s high level of histidine production is found to be associated with an unusually low level of production of other amino acids

C: others of the closely related group of plants are also found to produce histidine in large quantities

D: cultivation of the herb in soil with high concentrations of the metals will, over an extended period, make the soil suitable for plants to which the metals are toxic

E: the concentration of histidine in the growing herb declines as the plant approaches maturity

原文中说一组herb都是能抵抗XX，这组中某种植物是这样的情况，那如果这一整组都是这样的情况，不就加强了吗？

所以选C
