What is a scientific question ?

a- can cats learn to sit down on command
b-why do black cats bring bad luck ?
c- are spotted cats cuter than solid colored cats?
d- why are persian cats so funny ?

I think that the best answer would be A because it involves how they learn or how do their brains function, therefore can be answered by a Scientist. Choice B can be theories about how can a black cat can bring bad luck. Choice C can be defined real quick just by researching where do spotted cats genes come from. And finally choice D can be also a theoretical question.
