Answer:
The correct option is A) achondroplasia
Explanation:
Achondroplasia is a genetic disorder which is caused in an autosomal dominant pattern. This means that an individual who even has a single allele for the gene will have the disorder. This is because a dominant allele masks the effect of the recessive allele.
Achondroplasia is a disorder in which the cartilage of the long bones of the arms and legs does not get converted into bones. It is a type of dwarfism.
