Answer D. Asbestos exposure

Asbestos is a special type of long-thin silica crystal, usually of the mineral group chrysotile. In tissue, these crystals are highly irritative and highly fibrogenic. The fibers become coated with a protein-iron-calcium matrix, giving them a shish-kebab appearance. These are called "ferruginous bodies" because they are highlighted with an iron stain.
