Which of the following correctly defines a dangling modifier?

A dangling modifier is indeed defined as an introductory phrase that lacks a clear subject. This means that the modifier does not logically or grammatically connect to the noun it is intended to modify, leading to confusion or ambiguity in the sentence. For example, in the sentence "Walking down the street, the flowers were beautiful," the introductory phrase suggests that "the flowers" were doing the walking, which is not the intended meaning. Instead, it should clearly indicate who was doing the walking. When a modifier "dangles," it does not have a noun to attach itself to, which can mislead the reader about what the sentence is actually saying. This misunderstanding emphasizes the importance of ensuring that introductory phrases have a clear subject to enhance clarity and coherence in writing.
