Hi there!! Cilia are very small fine hairlike projection's/tissues, who's primary responsibilities in the airway is to make sure that it is clear. To be more specific... Cilia line the airways' trachea down. These cilia will do two things; They will trap germs and particulate matter (dust, dander, etc..), before then moving the trapped objects upward to the area where the airway meets the larynx, where you then swallow it... Additionally you can expel it eventually with a cough.
I would be answering what happened and why
Answer:
C. taste for salt and sugar.
Explanation:
the most common personal preference in the taste of food is salt and sugar amounts taken in a meal. Most of the people vary in their intake of salt and sugar. Other options such as desire for sour tastes, significant nutritional value and craving for protein are not common preferences for most people. Nutritional value for each meal is only sought by athletes or people who strictly needs to control it for professional purposes. A desire for sour is also not common in many individuals. A craving for protein is also less commonly seen.
