This has to be a dangler right? Please tell me I'm right.

I'd call it a runon or fused sentence.

B)runon

It doesn't fit my definition of a dangler. What do you mean by "dangler?"

subject not telling action.

Did you read and study the link Ms. Sue gave you? Even if you did, read it again ... and then rethink your last answer.

Actually, the statement you provided does not contain a dangler. A dangler is a type of misplaced modifier or phrase in a sentence that doesn't clearly and logically relate to the subject it's intended to modify or describe. It causes confusion or ambiguity in the sentence.

In the statement you provided, "Noah Webster supported himself through sales of his spelling book over 100 million copies of the book were sold," there is no misplaced modifier or phrase that would create a dangler. The sentence is clear and grammatically correct.

It states that Noah Webster supported himself through sales of his spelling book, and it also provides an additional piece of information that over 100 million copies of the book were sold. The two parts of the sentence are logically connected and make sense together.

If there were a dangler in this sentence, it might look like this: "Supporting himself through sales, over 100 million copies of Noah Webster's spelling book were sold." In this case, the phrase "supporting himself through sales" is not clearly connected to Noah Webster and could create confusion.

But in the original statement, there is no dangler present.
