This sentence is supposed to be grammatically wrong. Why is it so? What is the correct version?
Laughing does not typically report speech.
*She laughed a good idea.
?She laughed hello.
She said hello.
Since in this case, what stands for an argument to laugh, which is at best questionable.
You can repair this by changing either the verb, or what:
We asked because of why/when she laughed.
We asked because of what she said.
There are many more possibilities, but those two options probably change the sentence the least.
"Because of what" is not something you say often in English when "what" is a question. (It is often used when "what" refers to something: "I had to apologize because of what he did" - but it is not used to ask something, as in the original sentence.)
When asking a question, often you would use "why" instead
We asked why she laughed.
or more likely,
We asked why she was laughing.
Also, you don't laugh because of something, you laugh at it or about it. So
We asked what she was laughing at.
We asked what she was laughing about.
although as others have pointed out, you could laugh because of being tickled or inhaling laughing gas or whatever.
Grammar, dimly remembered from schooldays ...
In English, the fundamental structure of a grammatically correct sentence is [subject] [verb] [object]. Subject and verb are not optional, but some intransitive verbs do not accept an object. In "I took a biscuit", the subject is "I", the verb is "took" and the object (the thing that the verb is referring to) is "a biscuit". "Laughed" is intransitive. You can't laugh anything, you just laugh. If you laugh and [then] say something, that's exactly how you write it. 'She laughed, and said "Never!".'
Subject and object are frequently phrases rather than single words. In my first sentence above, "the fundamental structure of a grammatically correct sentence" is the subject.
The problem is that it's very rare to use the verb laugh transitively. It is possible for laugh to be used transitively, but it's usually (maybe even exclusively) used that way to qualify the laugh itself.
E.g., (from englishpractice.com)
This might be a stretch, but I'm trying to play with it a bit by composing something that might allow it to work in a certain context:
She laughed a laugh that was completely ridiculous; she laughed what was the loudest laugh we'd ever heard. We wondered, "Can this really be?" because what she laughed seemed impossible. We asked because of what she laughed.
Although other answers have pointed out that laughter does not convey speech, this is not necessarily true.
"You look like little red riding hood," he laughed.
"I like to be comfortable", he laughed.
"Yes, yes," he laughed, "I've been through the mill."
"Hello, sweet ladies," he laughed in a fruity, musical voice.
So the sentence is not technically ungrammatical.
Ordinarily the distinction is made between speaking and laughing, and certainly it's hard to speak intelligibly while laughing, so the sentence sounds quite odd.
The other answers assume you mean "We asked [a question] because of [what she laughed]".
However, I think what you actually mean is simply "We asked her why she laughed".
