How does the section in which King describes his feelings about the church, paragraphs 32-44, contribute to the development of ideas in the text?

A King expresses hope that the church will ultimately support the goals of integration, and this injects a sense of optimism into his letter.
B King questions the decisions of the church in regards to the civil rights movement, and this introduces uncertainty about whether the church will positively impact the future.
C King argues that the church continues to transform society by sharing the messages of God’s word, and this makes his claims more relevant to Christians.
D King examines the church’s response and decides that more work must be done to engage the church in the civil rights movement, which conveys the sense that the movement is not yet over.
