Which symbol represents Calcium?

Explanation:
Symbols for elements are the shorthand names of elements, usually one or two letters with the first letter uppercase and the second (if present) in lowercase. Calcium’s symbol is Ca, derived from its name, and written with a capital C followed by a lowercase a. This matches the standard formatting and uniquely identifies Calcium. The other symbols correspond to different elements—K is Potassium, P is Phosphorus, and Cl is Chlorine—so they do not represent Calcium.
