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.

Botulism can easily be prevented by boiling food prior to consumption.
<h3>What is Botulism?</h3>
Botulism may be defined as an imperative food poisoning that is provoked by botulinum toxin delivered in food by a bacterial species clostridium botulinum.
Clostridium botulinum inhibits the release of acetylcholine in the neuromuscular junction and causes defects in sensory perception through the central nervous system.
It can only be prevented by taking the proper boiled food prior to consumption.
The complete question is as follows:
- boiling food prior to consumption.
- administering antibiotics to patients.
- not eating canned food.
- filtering food.
- preventing fecal contamination of food.
Therefore, the correct option for this question is A, i.e. boiling food prior to consumption.
