The answer is option D "A reporter thinks she has a story but finds she doesn't have all the facts." A conflict is a problem or a situation and in this case option D would be a conflict because the reporter thinks she has a story but she doesn't have all the facts which is a problem. Isn't option A because a couple introducing their son to their parents isn't a problem, isn't option B because once again it isn't a problem for a bank robber to give up crime for his family, and it's also not option C because once again it isn't a problem that a veteran tells stories about his career as a Army Engineer.
Hope this helps.
