What is the primary cause of brittle bones?

1. Poor body mechanics.

2. Genetic disorder.

3. Burnout and exhaustion.

4. Exposure to excessive cold temperatures.

The correct answer is: Genetic disorder.

Brittle bones, often associated with a condition known as osteoporosis, are primarily caused by factors that affect bone density and strength. A genetic disorder can lead to conditions such as osteogenesis imperfecta, which causes bones to become fragile and break easily. This hereditary condition directly impacts the structure and formation of collagen, a critical protein in bone health. Other factors that can affect bone density include dietary deficiencies, hormonal changes, and lifestyle choices, but these generally arise from a variety of influences rather than being classified solely as genetic disorders. The presence of a genetic disorder highlights the underlying biological mechanisms that can predispose an individual to fragile bones, making it the primary cause in this context.
