Answer 1

The statement that states an important rule regarding colon usage is: a colon only introduces a list. The correct answer would be option B. The punctuation mark, colon (:) is typically used in the sentence to introduce a series of items in a list. But a certain rule should be followed. A preposition or a verb should not follow the punctuation mark, colon.
