OG verbal SC-89 虚拟语气和条件句求教

avenue5th

89.If Dr. Wade was right, any apparent connection of the eating of highlyprocessed foods and excelling at sports is purely coincidental.（D）

(A) If Dr. Wade was right, any apparent connection of the eating of
(B) Should Dr. Wade be right, any apparent connection of eating
(C) If Dr. Wade is right, any connection that is apparent between eating of

(D) If Dr. Wade is right, any apparent connection between eating

(E) Should Dr. Wade have been right, anyconnection apparent between eating

我选了B。OG答案中B选项写：Should Dr. Wade be right should not be followed by the present indicative verb is.
那请问应该用什么时态呢？

还有，我很难接受这个条件句和主句动词都是is啊！这个应该和OG12里面辩护律师行为不当那个不一样吧，那个是必然的客观事实，这个好像就是普通的条件句啊，为什么不是if... is, ... will be？求大牛赐教。。
