Answer: B) After I took a nice hot shower, my cat lapped up the water on the floor.
Step-by-step explanation:
As modifier is a word/phrase that describes a noun/pronoun, a dangling modifier is an ambiguous grammatical construction, in which it is not precisely stated which particular word is being modified.
In this particular case, we cannot tell whether it is the cat who took a hot shower or there is another person/animal who did it. In order for us to understand it better, this sentence should be paraphrased into a new one - After I took a nice hot shower, my cat lapped up the water on the floor. In this sentence, both of the actions ( taking a shower and lapping up the water) are linked to a subject. In this way, there is no confusion.
