Which level of kohlberg's stages of moral development suggests that moral reasoning is based on whether behavior is rewarded or punished?

Pre-Conventional

Explanation:

Three levels of moral reasoning were recognized by Kohlberg:

pre-conventional,  conventional and post-conventional. Increasingly complicated phases of moral  development are connected with each stage.

The sense of morality of a child is externally regulated throughout the pre-conventional stage.

Children recognize parents and educators as figures of power and accept and believe their rules.  A kid with pre-conventional morality has not yet embraced or  fully accepted the conventions of society about what is correct or incorrect,  but instead focuses mainly on the external effects that some actions may bring.
