Final answer:
Martin Luther King Jr. is the minister who skipped 9th and 12th grade and enrolled in Morehouse College at age 15, distinguishing himself from Malcolm X, who became a minister after prison.
Step-by-step explanation:
The minister who skipped 9th and 12th grade before entering Morehouse College at age 15 was Martin Luther King Jr. Unlike Malcolm X, who became associated with the Nation of Islam during his time in prison and was a strong voice in the civil rights movement, Martin Luther King Jr. pursued a path of non-violent protest and entered college at a young age after skipping two grades in high school. Malcolm X's history is significant due to his influential role as a minister of Islam and a key leader who voiced the concept of African Americans taking control of their communities and being self-reliant. However, in the context of the question, it is Martin Luther King Jr. who was known for his advanced educational achievements, including enrolling in Morehouse College as a young teenager.
