C. An audience will be listening to their writing
Answer:
C) A career in politics, which was not his first career, ended up being the ticket to success for Abraham Lincoln.
Explanation:
In the sentence shown in the question above, the information considered to be non-essential is "... which was not his first career ..." This statement is considered non-essential because it is not necessary for us to understand the context of the sentence and the message that must be passed. This type of information must always be accompanied by two commas, one at the beginning of the information and one at the end, as shown in option C.
It is not correct to use the symbol ";" in place of the comma, in this case, since this symbol should not be used to separate non-essential information.
