Answer

Correct answer: b) Both A & R are correct but R is not reason for A

Both statements are correct, but R is not the reason for A. Hyperparathyroidism causes hypercalcaemia, which leads to metastatic calcification (deposition of calcium salts in otherwise normal tissue) — this is correctly stated in A. R is also true, but describes a separate, unrelated concept: dystrophic calcification (deposition of calcium in damaged/necrotic tissue) occurs despite normal serum calcium levels, which is precisely what distinguishes it from metastatic calcification, not what explains why metastatic calcification occurs in hyperparathyroidism.
