It could just be my perspective, but it seems like "Disjointed" could fit well.
For an opinion to be substantiated, you need supporting evidence or a reference to validate it. Option A qualifies as it mentions a verifiable fact by suggesting that one can check with the large computer company to see its origin. More evidence would be required to substantiate the claim that small businesses are the backbone of America's strong economy.

John Brown was an American abolitionist who supported rebellion as a means to eradicate slavery in the United States. He faced charges of treason against the Commonwealth of Virginia for his unlawful actions, was convicted, and executed by hanging.
In the time leading up to his execution and following his conviction, a significant number of notable individuals campaigned financially and crafted speeches in his support. Notable amongst them was Ralph Waldo Emerson. Emerson depicted Brown as a relatable, ordinary person driven by strong beliefs to take action. This portrayal was meant to highlight Brown’s admirable qualities and generate empathy from the public by making a connection with themselves.
