C Correct answer
Explanation

Diatoms have several industrial applications due to their silica-based cell walls. They are used in insulation materials (diatomaceous earth for pipes and refrigerators), fire-resistant materials, and historically in dynamite preparation (to stabilize nitroglycerin). Diatoms are not used for food preparation - they are microscopic algae collected for industrial uses, not culinary purposes.
