Answer:
D. It attempts to modify something or someone unknown to the reader.
Step-by-step explanation:
Modifiers are used to alter or change the meaning of sentences. Adjectives and adverbs can serve as modifiers. Dangling modifiers, however, are unclear as to what they truly modify. In the sentence below;
The girls left immediately.
"Immediately" is an adverb that modifies the verb, "left".
Dangling modifiers do not have the object being modified present. If we only said,
"Immediately"
a person might be confused about what we are saying. This is a dangling modifier. But if we said,
"Immediately, the girls left".
The meaning is better comprehended.
