Answer:
E. postconventional
Step-by-step explanation:
Blake is at a postconventional level of personal moral development according to Kohlberg's model.
In the postconventional level of moral development, people have established personal ethical and moral ideals, and live by those, not necessarily by what is established within a society.
For this reason, they may hold unusual views, and Blake is described in the question as being an independent thinker, which is consistent with the characteristics of this stage.
