Question

which of the following is considered an electrolyte?
○ a. prednisone
○ b. adrenaline
○ c. corticosteroids
○ d. phosphorus

Explanation:

Electrolytes are substances that ionize in solution (like in body fluids) and conduct electricity. Prednisone (a), adrenaline (b), and corticosteroids (c) are hormones or drugs, not electrolytes. Phosphorus (d) is a mineral that can ionize (e.g., as phosphate ions) and acts as an electrolyte in the body, involved in processes like energy transfer and bone health.

Answer:

d. phosphorus
