الإجابة: A. Primary hyperparathyroidism
Bone pain, renal stones and peptic ulcer (bones, stones, groans) with high calcium and low phosphate is classic primary hyperparathyroidism. Secondary hyperparathyroidism has low or normal calcium, and vitamin D toxicity and sarcoidosis do not lower phosphate in this way.

ليش غلط
Vitamin D increases intestinal absorption of both calcium and phosphate, so vitamin D toxicity (hypercalcemia, hypercalciuria, loss of appetite, stupor) does not explain the low phosphate here.

Sarcoidosis typically presents with fever, cough, dyspnea, malaise, weight loss and arthritis, with bilateral hilar adenopathy on chest X-ray; nothing in this stem suggests it.
