问题如下：
When NPV profile intersects with the horizontal axis, it represents:
选项：
A.the cost of capital at which two projects’ NPVs are equal.
B.the NPV when cost of capital is zero.
C.the IRR when NPV is zero.
解释：
C is correct. NPV profile shows a project’s NPV graphed with different discount rate. The NPV is graphed vertically, and discount rate is graphed horizontally. Therefore the intersection point with horizontal axis is the cost of capital where NPV is zero, which is IRR of the project.
老师好 horizontal axis is the cost of capital where NPV is zero是为啥，可不可以画图看一下，谢谢您
