what made standard oil a horizontal integration monopoly?\no it owned ninety percent of us oil refineries.\no it controlled all aspects of oil production.\no it operated all across the united states.\no it formed a trust.
Answer
Brief Explanations:
Horizontal integration involves combining firms in the same stage of production. Owning 90% of US oil refineries means Standard Oil combined many refineries (same - stage production), creating a monopoly. Controlling all aspects of oil production is vertical integration. Operating across the US doesn't define horizontal integration. Forming a trust is a method but not what defines it as horizontal integration monopoly.
Answer:
It owned ninety percent of US oil refineries.
