The answer to your question would be that the literary device that enables readers to have mulitiple interpreations of a word, phrase, or event is the following one: ambiguity. That is, the correct option would be C.

It is the act or process of moving faster or happening more quickly the act or process of something
I believe the answer to this question would be either a metaphor, idiom, or alliteration. But this would most likely be idiom because people can interpret different meanings of this phrase negative or positive and can take it personally or extensively.
