Autosomal dominant trait-linked disorders are caused by the presence of a single copy of a mutated gene on one of the autosomes. Inheritance of these disorders does not depend on the sex of the individual. Examples of autosomal dominant trait-linked disorders include Huntington's disease, Marfan syndrome, and familial hypercholesterolemia. Hence option 3 is the correct answer.

Explanation for the incorrect options : 

Option 1 is incorrect because Hemophilia A is an X-linked recessive disorder.

Option 2 is incorrect because Duchenne muscular dystrophy is an X-linked recessive disorder.

Option 4 is incorrect because cystic fibrosis is an autosomal recessive disorder.
