可是我记得以前有一个由OG得出的说法是

主语从句中谓语动词是单数的话，主句谓语就用单数

what brings us good luck is dogs.

主语从句中谓语动词是复数的话，主句谓语就用复数

what bring us good luck are dogs.

这又让我对于D的答案有点迷惑，大家帮帮忙！！

lz 从句做主语的时候，谓语动词一般情况下是用单数的。
但是what who等引导的主语从句含有复数意义的时候，动词可以用复数的形式。
所以不是绝对的。

(D) What scientists know about dinosaur brains comes from studies of the cranium, the bony house of the brain located in the back of the skull.
"what scientists know about dinosaur brains" 其实是 a thing，some knowledge，做主语时谓语用单数comes from
主语从句中的小主语是scientists，小谓语由此决定为know。what其实是做主语从句的宾语。

而你的举例中
what brings us good luck is dogs. 中的主语从句中what做小主语，此时主句谓语也由该what来决定。
what bring us good luck are dogs. 中的主语从句中，也是what做小主语。因此主句谓语和从句谓语保持一致。
