b. Increased excretion of phosphate in the kidneys.

d. Increased deposition of calcium into the bones.
c. Increased reabsorption of phosphate in the kidneys
d. Increased deposition of calcium into the bones.
Explanation:
Hyperphosphatemia is a condition that is expressed particularly in people with a kidney dysfunction. It comprises the kidneys, which do not excrete enough phosphate from the body as they reabsorbe it and thus leading to increased phosphate levels.
Also, phosphate binds calcium with high affinity, provoking acute hypocalcemia (decreased levels of calcium). In Hyperphosphatemia, calcium is being deposited mostly in the bone but also in the extraskeletal tissue.
