Which of the following explains the difference between a carrier of a sex-linked disorder and a carrier of an autosomal disorder?

The choices can be found elsewhere and as follows:

A- All children of a male autosomal carrier will express the disorder.
B- All children of a female autosomal carrier will express the disorder.
C- All carriers of sex-linked disorders are females who do not express the disorder.
D- All carriers of autosomal disorders are females who do not express the disorder.

I think the correct answer is option C. All carriers of sex-linked disorders are females who do not express the disorder explains the difference of those terms. Hope this helps.
