What tone do these lines convey?

Well, children, where there is so much racket there must be something out of kilter. I think that 'twixt the negroes of the South and the women at the North, all talking about rights, the white men will be in a fix pretty soon. But what's all this here talking about?

Aa formal and reserved tone

Ba conversational and inquisitive tone

Ca dissatisfied and pessimistic tone

Da hopeful and idealistic tone
