I'm also considering (D). Is it wrong because Maria does not mention that using cloth diapers is a "far more serious" treat ? So, this answer is exaggerate.
However, for (B), I think Pedro does not show any evidence about the cloth diapers. He is in favor of cloth diapers due to the disadvantages of disposable diapers. So, I was wondering where is the inadequate evidence about cloths diapers ?
Could anyone help?
Thanks
