The purpose of hairs lining the nasal cavity is best described by option **B**: to help trap dust, mold, and pollen before they can reach the inner portions. These hairs, or nasal cilia, help filter out particles and pathogens, contributing to the overall function of the respiratory system in protecting the lungs.
