Here are the essential concepts you must grasp in order to answer the question correctly.
Osteoporosis
Osteoporosis is a bone disorder characterized by decreased bone density and quality, leading to an increased risk of fractures. In this condition, the bones become porous and fragile, but the mineral composition remains normal. It is often associated with aging, hormonal changes, and nutritional deficiencies, particularly in calcium and vitamin D.

Osteomalacia
Osteomalacia refers to the softening of bones due to inadequate mineralization, primarily caused by a deficiency of vitamin D, calcium, or phosphate. Unlike osteoporosis, where bone density decreases while composition remains normal, osteomalacia results in a change in the bone's structure, making it weak and more prone to deformities and fractures.
Paget's Disease
Paget's disease is a chronic disorder that disrupts the normal cycle of bone renewal, leading to enlarged and weakened bones. It typically affects older adults and can result in pain, deformities, and an increased risk of fractures. The bone composition may be altered, with areas of excessive bone formation and others of resorption, distinguishing it from osteoporosis.
