Hint: Scientists developed a short-hand way to represent chemical elements in the periodic table and called it a chemical symbol. There is more than one reason behind the development of the chemical symbols for the elements by the scientists.

Complete step by step answer:
- One of the main reasons to develop the chemical symbols is we can represent the elements easily and another reason is by using symbols we can write the chemical formulas simply.
- The chemical symbols are universal means they are the same all through the world and we can identify them easily.
- Till now 112 elements are identified and all the elements have several reactions and various properties, to study those there is a need of symbols for the elements to represent.
- In the question it is given that we have to write the symbol for the element copper.
- Coming to the given options, option A, C. C symbol is used to represent the chemical Carbon.
- Coming to option B, Ca. Ca symbol is used to represent the chemical Calcium.
