The chemical symbol for calcium is represented as "Ca." This symbol is derived from its Latin name, "calcium." Each element on the periodic table is assigned a unique chemical symbol, typically consisting of one or two letters; in this case, the first letter is uppercase and is accompanied by a lowercase letter.

The choice A represents the correct symbol used in various scientific, educational, and chemical contexts to denote calcium, which is a vital element found in many biological systems and is essential for bone health in humans and animals. This understanding of chemical symbols is fundamental in chemistry as well as in fields that involve animal care and control, where knowledge of nutritional requirements for animals can be essential.

In contrast, the other choices provided are symbols for different elements: "C" represents carbon, "Co" represents cobalt, and "Cu" represents copper, all of which serve distinct and important roles in chemistry and biology but do not refer to calcium. Recognizing these symbols and their corresponding elements is crucial for anyone studying or working within the fields of animal control and care.
