Show answer and explanation
Correct answer: A. Oral mucosa (epithelium)

- B. Oral EPITHELIUM (mucosa) is derived from ECTODERM — NOT mesenchyme. Bone, cartilage, muscle (skeletal), dentin, pulp, cementum, periodontal ligament are mesenchymal derivatives (from cranial neural crest cells in the head region).
- C. Bone is a classic mesenchymal tissue.
- D. Skeletal muscle is derived from mesoderm/mesenchyme — it IS a mesenchymal derivative.
