Condition which makes bones weak and more likely to break.

• A. Sprain
• B. Osteoporosis
• C. Strain
• D. Orthopedist

Answer: (B)

Weak bones that are prone to breaking come from osteoporosis. In this condition, bone density decreases and the internal bone structure becomes porous and fragile, so even minor bumps or falls can cause fractures. It often affects older adults, especially postmenopausal women, due to hormonal and nutritional factors, but it can occur in others as well. Because osteoporosis is a system-wide loss of bone strength, it increases fracture risk in many bones, not just one joint or muscle.

Sprain is an injury to ligaments, strains are injuries to muscles or tendons, and an orthopedist is a clinician who treats musculoskeletal problems—not a condition that weakens bones.
