请教大家这个是不是虚拟语气

If Dr. W was right, any apparent connection of the eating of highly processed foods and excelling at sports is purely coincidental.

b should Dr W be right, any apparent connection of eating

c If Dr w is right, any apparent connection between eating

d should Dr w have been right, any connection apparent between eating

应该选什么

答案是c， 但我认为至少应该把is换成 were

所以我开始选的是d.这个结构错在哪里呢？请大家发表意见

哦，，忘记了好多东西。。。

多谢你啊~~
