Hypocalcemia refers to

Explanation:
Hypocalcemia refers to a lower-than-normal calcium level in the blood. Calcium is essential for bone structure, nerve signaling, muscle contraction, and heart function, so when calcium is low, nerves can become overexcitable and muscles may cramp or spasm, with more serious effects possible if levels stay low. Among the options, only low calcium describes hypocalcemia; the others describe high calcium or altered sodium, which are not related to hypocalcemia.
