The electronics company has unveiled what it claims to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs less than 11 ounces.

1. to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs
2. to be the smallest network digital camcorder in the world, which is as long as a handheld computer, weighing
3. is the smallest network digital camcorder in the world, which is as long as a handheld computer, and it weighs
4. is the world’s smallest network digital camcorder, which is as long as a handheld computer and weighs
5. is the world’s smallest network digital camcorder, the length of which is that of a handheld computer, weighing

晕,给出的答案选b,不知道这里的weighing,是修饰谁的,有点模糊.我选了d感觉weigh更清晰些是修饰camcorder的

i chose D too.

weighs should be parralled with is.

D is correct answer.

B ,weighing is not correct usage of participle here

B没有D好，原因如下：

1，in the world介词短语的位置，导致which定语从句首先就近修饰world;

2，weighing从语法角度可以理解为前面名词a handheld computer的定语，不合逻辑；也可以理解为现在分词做伴随状语，从句意分析伴随结果不合逻辑，伴随动作的话也不合理，因为前面的to be 是一种状态，后面的weighing是动作

相比较而言，D逻辑修饰关系清晰，而且句子简洁没有歧义
