(D) is the world's smallest network digital camcorder, which is as long as a handheld computer and weighs

答案选d 可是我却不是很清楚这个句子的结构has unveiled what it claims is ? 如果unveiled 后面加的是从句，不是要加that?

我觉得to be 的结构很好， has unveiled what it claims to be , what 作unveild的宾语，it claims to be修饰what。 为什么不对呢？

the point lies on "which is as long as a handheld computer and weighs". since the length and the weighth are parallel logically, they should also be parallel grammatically. only d is correct.

is the world's smallest ... is the object clause of claim. that is, the compant claims that "what" is the world's smallest ...
