Final answer:
Lawrence Kohlberg's moral development theory progresses from preconventional to postconventional levels, possibly indicating complex morality as a luxury for those not focused on survival, although Kohlberg does not directly state this. The conventional level involves societal norms guiding morality.
Step-by-step explanation:
The child moral development theory that suggests morality is essentially a luxury for those who live without want or fear doesn't appear to be directly addressed in the given materials. However, the provided information outlines Lawrence Kohlberg's stages of moral development, where morality evolves through preconventional, conventional, and postconventional levels. It's in the postconventional stage where individuals think of morality in abstract terms and recognize that legality and morality do not always align. This abstract thinking about moral principles could suggest that more complex moral reasoning is available to those who are not preoccupied with basic needs or survival, which aligns with Maslow's hierarchy of needs in psychology. However, this specific connection is not explicitly made by Kohlberg.
With reference to the multiple-choice question provided, option c is the correct answer: In Lawrence Kohlberg's conventional level, children begin to consider what society considers moral and immoral.
