Looking at this question from a 2008 Ruse Half-yearly I get why the answer is C, but only through process of elimination. If one of the possible answers was regular dominant, I wouldn't know the answer. Is it even possible to definitively say that the condition is sex-linked dominant instead of plain dominant?

Is there a way to tell if a condition is sex-linked or not beyond a disproportionate amount of males being affected or it only being passed through the female line? Because it seems like that could happen with a non-sex-linked recessive gene just because of probability.

Nah not really, if the question did have both dominant and sex-linked dominant then the answer could have been either but it doesn't so don't worry about it. They sometimes put questions that have more than one answer but by limiting your choices you can only choose to have one answer as the right one.
