Who among the following proposed the theory of moral development among children?

Correct option is C

Lawrence Kohlberg
Lawrence Kohlberg is renowned for his theory of moral development, which expanded on Jean Piaget's work. Kohlberg's theory proposes that moral reasoning develops through a series of stages, from a pre-conventional level focused on self-interest and avoidance of punishment, to a conventional level where societal norms are accepted, and finally to a post-conventional level where universal ethical principles are recognized. This theory differs from the ideas of Konrad Lorenz (ethology), Sigmund Freud (psychoanalysis), and Erik Erikson (psychosocial development), who focused on different aspects of psychology and development.
