Correct Answer: Option A

Explanation

The correct answer is A. Albinism.

Albinism is an autosomal recessive disorder, meaning it's caused by a mutation in a gene located on a non-sex chromosome (autosome). It's not sex-linked, although, some types of albinism are sex-linked. e.g ocular albinism.

The other options are sex-linked:

 B. Baldness: Androgenetic alopecia, a common form of baldness, is influenced by genes on the X chromosome.

 C. Haemophilia: Haemophilia A and B are caused by mutations in genes on the X chromosome.

 D. Colour blindness: The most common forms of color blindness are caused by mutations in genes on the X chromosome.

So, albinism is the correct answer.
