when are colons used? select three options. a colon separates clauses in a series. a colon signals that a list follows. a colon appears in 12 - hour time notations. a colon is used after an introductory phrase. a colon follows the greeting in a formal letter.
Answer
Brief Explanations:
Colons signal lists, are in 12 - hour time notations, and follow greetings in formal letters. They don't separate clauses in a series (semicolons do that in some cases) and are not used after an introductory phrase (commas are more common there).
Answer:
B. A colon signals that a list follows. C. A colon appears in 12 - hour time notations. E. A colon follows the greeting in a formal letter.
