The answer is option letter B (heartfelt). Feature stories not only convey facts but also narrate the story of someone’s life. In order to fulfill that purpose, the writer uses background information, quotes, and anecdotes. If the actions and emotions described in a feature story are very sincere, that is heartfelt, it will allow the writer to make up a creative opening full of anecdotes and memories for it. In fact, a creative opening will call the reader’s attention and make him/her want to read more features stories.
