B. one that is repeated throughout the text
C. one that occurs in the particular story and in other stories

Answer 1

An implicit theme is when the work is implied, rather then expressed. So I would say D is the most appropriate answer. 

Answer 2

An implicit theme IS one that is suggested through character and plot development . Option D is the correct option.

That means that the theme is not clearly stated and identified by the reader, you must think about the story to find the theme.

An implicit theme entails a merely implied theme. A theme that is not expressed. This type of theme may contain hidden meanings that is being inferred in the text.
