Yes. It is common for a normal, healthy individual to carry potentially pathogenic organisms in their upper respiratory tract.
The human upper respiratory tract serves as a reservoir for a diverse community of commensals and potential pathogens, such as Haemophilus influenzae, Moraxella catarrhalis,etc. which can occasionally develop into pathogens and cause infectious diseases. Viruses are responsible for the majority of upper respiratory tract infections.
Nasal hairs are used to catch debris. Particles are propelled upward and out of the respiratory tract by cilia on the epithelium of the trachea and bronchi. The respiratory system has a feature that guards against infections.
Therefore, It is common for a normal, healthy individual to carry potentially pathogenic organisms in their upper respiratory tract.

Answer:
Prions are abnormally shaped proteins that cause spongiform encephalopathies. (Ans C)
Explanation:
Prions : Prions are proteinaceous infectious particle or misfolded proteins with the ability to transmit their misfolded shape into normal shape protein. They are also responsible for some neurodegenerative diseases in mammals. They can affect both animals as well as humans.
Prion disease occurs when normal prion protein (present on the surface of many cells) becomes clump (abnormal) in the brain. This accumulation of abnormal protein in the brain can cause disease.
Spongiform encephalopathies also called prion disease. Spongiform encephalopathies affect the nervous system and brain of animals & humans. It is caused by a degeneration of brain tissues giving it a spongy appearance.
