Suppose that two supply curves pass through the same point. One is steep, and the other is flat. Which of the following statements is correct?<br/> A、The flatter supply curve represents a supply that is inelastic relative to the supply represented by the steeper supply curve.<br/> B、The steeper supply curve represents a supply that is inelastic relative to the supply represented by the flatter supply curve.<br/> C、Given two prices with which to calculate the price elasticity of supply, that elasticity would be the same for both curves.<br/> D、A decrease in demand will increase total revenue if the steeper supply curve is relevant, while a decrease in demand will decrease total revenue if the flatter supply cure is relevant.
