Answer: (E)

Verified step by step guidance

1. Begin by understanding the key terms related to bone conditions: osteopenia, osteomalacia, osteomyelitis, osteitis, and osteoporosis.
2. Osteopenia refers to a condition where bone mineral density is lower than normal but not low enough to be classified as osteoporosis.
3. Osteomalacia involves the softening of bones due to defective bone mineralization, often due to a deficiency of vitamin D or calcium.
4. Osteomyelitis is an infection in the bone, typically caused by bacteria, leading to inflammation and potential bone destruction.
5. Osteitis refers to inflammation of the bone, which can be due to various causes, including infection or trauma. Osteoporosis, however, is characterized by a significant reduction in bone mass and density, leading to fragile bones and an increased risk of fractures, which aligns with the condition described in the problem.
