The correct answer is C. Determine what language is appropriate by carefully observing and listening to others
Explanation:
In English and other languages, the election of words and expressions, the tone and the way a message is organized leads to a general style in language or communication. This style is usually classified as formal or informal, while informal language is used in informal contexts such as family or friends and uses words and grammar in a spontaneous and relaxed way, formal language uses more sophisticated vocabulary, always follows grammar rules and avoids slangs or non-formal expressions, which is used in serious situations such as job or academical context. Considering workplace mainly involves the use of formal language but does not excludes completely the use of informal language and the level of formality can vary depending on who you are speaking to it is better to determine whether you should use formal or informal language by observing the way people use language and imitating their style, in this way if you observe everyone uses only formal language you should do the same as informality would be considered as inappropriate. Also, if you do not have enough information or you are speaking with superiors it is a good idea to use formal language.
