Which option is the phonetic pronunciation of "C"?

The phonetic pronunciation of the letter "C" is represented as "Charlie" in the NATO phonetic alphabet, which is designed to ensure clarity in communication, especially when spelling out words over radios or telephones. Each letter in the alphabet is associated with a unique word to avoid confusion that might arise from similar-sounding letters.

Using "Charlie" for "C" helps others to clearly understand and differentiate it from other letters. The other choices, while they are words that start with the letter "C," do not serve the purpose of representing the letter phonetically in a standardized format. In aviation and military contexts, clarity is crucial, and "Charlie" delivers this effectively, making it the correct choice for the phonetic representation of "C."
