24-7 Which of the following most logically completes the argument below?

The expansion of large-scale farming in LACE>AfricaLACE> and LACE>AsiaLACE> has destroyed much of the natural vegetation on which elephants have historically depended, forcing them to turn to cultivated land to satisfy their enormous appetites. As a result, farmers have lost millions of dollars worth of crops annually. Yet even if elephant sanctuaries were created on a widespread basis to guarantee elephants sufficient natural vegetation, the raiding would likely persist, since

(A) when elephants forage for food, they typically travel in herds.

(B) foraging elephants have been known to cause substantial damage even to plants that they do not eat.

(C) some of the land where crops have suffered extensive damage from elephants has been allowed to return to its natural state.

(D) elephants tend to prefer cultivated crops to wild vegetation as a food source

(E) elephant sanctuaries are usually created in areas that are rich in the natural vegetation on which elephants have historically depended.

答案是D，没有问题，但是想问问B选项错在哪里？

我觉得如果大象对即使不吃的植物都进行破坏的话，糟蹋粮食的事情还是会继续发生的。

不明白:不四处觅食只呆在根据地里那大象怎么吃得到粮食?这样的话D还有意义吗?

大象因为有食物偏好，所以有可能走出根据地去吃庄稼.

many  thanks !!!
