Please attach balloons to these places: the front door, the mailbox and the lamppost.
Answer:
The sentence that has correct punctuation is the last one (Please attach balloons to these places: the front door, the mailbox, and the lamppost.)
Explanation:
A colon means "that is to say". In this case, the colon has been used to introduce an item or series of items. Â The NPs after the colon are the places to which the balloons should be attached. You should not capitalize the first item after the colon unless it is a proper noun.
