Final answer:
Hyperparathyroidism is a condition characterized by high levels of parathyroid hormone, excessive calcium removal from bones, and impaired nervous system. The correct answer is d) Hypercalcemia, osteoporosis, abdominal discomfort.
Step-by-step explanation:
Hyperparathyroidism is a condition characterized by an overproduction of parathyroid hormone, resulting in excessive calcium being removed from bones and introduced into the bloodstream. This leads to structural weakness of the bones, which can cause deformities and fractures. It also impairs the nervous system due to high blood calcium levels. The correct answer is d) Hypercalcemia, osteoporosis, abdominal discomfort.
