[求助]PREP1-151 双重所有格可以对吗？

151.     (33055-!-item-!-188;#058&006544)

Like the thorny ballooning of a frightened pufferfish or the sudden appearance of angry sapphire hoops for which the blue-ringed octopus is named, so the California newt's display of its red underbelly is a clear warning that predators ignore at their peril.

(A) so the California newt's display of its red underbelly is a clear warning that predators ignore at their peril

(B) so it is at their peril that predators ignore the California newt's display of its red underbelly, a clear warning

●(C) the California newt's displaying its red underbelly is a clear warning for predators, so they ignore it at their peril

 (D) the California newt's display of its red underbelly is a clear warning that predators ignore at their peril

(E) it is at their peril that predators ignore the California newt's display of its red underbelly, a clear warning

我选C，知道对比不太完美，但是D中不是有双重所有格吗？

正确答案：D

首先 lz对双重所有格认识有误 双重所有格是of和xx’s放在一起才是啊 比如friend of my sister's

题目中的its只是修饰red underbelly 而已啦

其次  newt's displaying its red underbelly   中display 明明有自己的名词形式再用displaying来表述其的名词形式是错误的

再次 C中的it和they 都 指代不清

再再次 D更为紧凑和连贯
