your answer here is "colon." this punctuation mark ( : ) is used to set off lists or offer further information, but you must lead into it first. for example:
i need three things from the store: eggs, butter, and salt.
The colon extends a preceding sentence, usually presenting a list that demonstrates or details what has been reconfirmed. The colons are also used to separate time from minutes in writing times from numbers. In this question, the first use mentioned is the one that would fit the answer.
