Why is Answer-choice A eliminated?

Hi, Answer choice A also weakens the opponents' argument that the relationship between performer and audience will be abolished. Lines 26 to 30: "Some even worry that technology will eliminate live performance altogether; performances will be recorded for home viewing, abolishing the relationship between performer and audience." In weakening the opponents' argument, quoted above, I call your attention to "abolishing the relationship between performer and audience." If we can show that the technology will not affect this relationship between audience and performer, or if we can show that technology enhances it, then we can weaken the opponents argument that technology will result in abolishing this relationship. No? Answer-choice A states: "Surveys show that when recordings of performances are made available for home viewing, the public becomes far more knowledgeable about different performing artists." Well, when the public or audience becomes "far more knowledgeable about different performers as the result of technology, wouldn't that mean that mean that the public's relationship with these performers is strengthened, which is contrary to the opponents' forecast? In retrospect, if we can show that technology enhances the relationship between performer and audience, as answer-choice A states, we then weaken the opponents argument that technology will abolish that relationship can also weaken the opponents argument by showing that technology will not affect the relationship between performer and audience, Answer-choice D works too as it states: "The distribution of recordings of artists' performances has begun to attract many new audience members to their live performances." But what makes D superior to A? Please help with this. Thank you in advance
