all of the following to find a theme of a story, except options are the central idea of a work, the underlining message in literature, the messages of Care, isolation, employed by the writer, the lesson or moral of the story, which can be inferred by readers

The options provided can all help in finding the theme of a story. However, the option "the messages of care, isolation, employed by the writer" may be the exception in this case. While care and isolation can be themes of a story, it is not a common practice to refer to them as "messages employed by the writer." The other options mentioned, such as the central idea, underlying message, and the lesson or moral of the story, are commonly used to describe the theme of a story.

The option that does not help in finding the theme of a story is "the messages of care, isolation, employed by the writer." While care and isolation may be elements within a story, they do not directly assist in identifying the theme. The other options listed—central idea, underlying message, lesson or moral of the story—can all contribute to discovering the theme.
