**Option C:** Not given, but renal tubular acidosis is a known cause.
**Option D:** Not specified, but it's essential to consider the typical causes.

**Clinical Pearl / High-Yield Fact**
Nephrocalcinosis is often associated with conditions leading to hypercalcemia, such as primary hyperparathyroidism. Recognizing these associations is crucial for diagnosis.
