4. I, II and III are correct
| I: | In bone, PTH enhances the release of calcium from the large reservoir contained in the bones. |
| II: | In the kidney, PTH stimulates reabsorption of calcium but inhibits the reabsorption of phosphate \((HPO^{2-}_4)\) from the tubular fluid. |
| III: | It activates vitamin D, which in turn enables intestinal epithelium to absorb calcium. |
