Correct answer: C — Osteoclast
Osteoclasts are large multinucleated cells derived from the monocyte-macrophage lineage. They resorb bone by creating an acidic environment via hydrogen ion secretion (ruffled border) and releasing enzymes such as tartrate-resistant acid phosphatase (TRAP) and cathepsin K. Osteoblasts form bone; osteocytes are mature embedded osteoblasts.
