Verified step by step guidance1
Understand that chemical symbols are one- or two-letter abbreviations derived from the element's English or Latin name.
Recall that 'Co' stands for Cobalt, 'Cr' stands for Chromium, and 'C' stands for Carbon.
Recognize that the chemical symbol for copper is derived from its Latin name 'Cuprum', which is represented as 'Cu'.
Compare each option with the known symbols to identify which corresponds to copper.
Conclude that the correct chemical symbol for copper is 'Cu'.
