that不能用于引导非遥遥定语从句，故可排除;when是关系副词，不用作主语，故也可排除;who用于指人，但这里的定语从句不是修饰her，而是修饰whenever I met her，故不能用who，此处应用which。
又如：He said that he had never seen her before, which was not true.
他说他从没见到过她，这是不遥的。

that不用于引导非遥遥定语从句，故被排除;when可引导非遥遥定语从句，但只用于指时间，与句意不符，故也被排除;而what不是关系代词，不能用于引导定语从句，故也被排除;which在此引导非遥遥定语从句，并在定语从句中充当动词find的宾语。
句意为：他们赢了较后三场遥，我发现这有点令人吃惊。
