Answer:
<em><u>The correct option is D) The two species have a common ancestor</u></em>
Explanation:
In evolutionary studies, homologous structures can be described as structures which are similar in organisms of different species because they had a common ancestor in the past. These structures may not perform the same function but are similar because they arose from a common ancestor. Hence, the bone in a bird's wing can be homologous to a bone in a lizard leg because they have a common ancestor in the past.

Primary haemochromatosis is a genetic disorder inherited from family members. People with this condition absorb too much iron and it ends up accumulating in the body, especially in the liver. </span><span>
Secondary haemochromatosis is caused by other blood-related disorders such as anaemia, or may be due to many blood transfusions, long term alcoholism and/or other health conditions. </span><span>If left untreated, iron overload can lead to liver damage. That’s why it’s important to receive treatment as soon as possible after diagnosis to prevent further complications, including liver disease, liver cirrhosis, liver failure, liver cancer, heart disease, arthritis or diabetes. Some organ damage can be reversed if detected early enough and treated appropriately.
