Solution

The correct option is C Ciliated epithelium
Ciliated epithelium is present in the respiratory tract which helps to sweep away the dust particles outside the body that were caught in the mucus. Cuboidal, glandular and squamous epithelium are absent in the nose and are not involved in the sweeping of dust.
Therefore, the correct answer is option C.
