During laboratory analysis, removal of collagen fibers from a bone leaves it hard but easily broken. This finding shows that collagen primarily provides:

A. Bone hardness
B. Bone elasticity and tensile strength
✓
C. Bone mineral storage
D. Blood cell production

📝 Explanation

Correct: Collagen gives bones flexibility and resistance to breaking. A: Hardness is due to mineral salts. C: Minerals are stored in bone, not collagen. D: Blood cells are produced in bone marrow. Concept: Role of collagen in bone.
