Which word best matches the meaning of "credible" in the context of the story?

The word "credible" refers to something that is believable or worthy of being accepted as true. In the context of a story, if a character or situation is described as credible, it suggests that the details are convincing and the storyline is realistic enough to be accepted by the audience. This notion is fundamental in storytelling, as it ensures that readers can engage with the narrative without question.

The other choices do not align with the meaning of "credible.” "Amazing" implies something extraordinary or surprising, which does not directly relate to the truthfulness or believability of a statement or story. "Dirty" refers to something unclean or soiled, and "crumbly" describes a texture that breaks apart easily, both of which are unrelated to the concept of being believable. Thus, "believable" is the best match for the meaning of "credible" in this context.
