Answer:
The correct answer is Continuity.
Step-by-step explanation:
In creative writing, an element that has to remain consistent throughout a story (i.e. a physical trait) is set by continuity.
There are many methods to avoid continuity errors in storytelling. However, most of the time it can be corrected by maintaining close attention to the details and keeping notes on the major elements of characters, scenes, and passage of time.
In the case of physical and psychological traits for characters, it is a good idea to create character sheets with a detailed description of each one, including background story, beliefs, family and friends, and any other important facts.
