Which choice exemplifies the correct trigger for using a colon?

• A. She will need these items: soap, towels, and shampoo.
• B. It is true: that she will succeed.
• C. Look at this: fantastic opportunity.
• D. This is therefore: the result of hard work.

Answer: (A)

The choice that exemplifies the correct trigger for using a colon is one that correctly introduces a list or an explanation that follows a complete sentence. In option A, the phrase preceding the colon, "She will need these items," stands as a complete sentence that clearly sets up what follows. The colon is appropriately used to introduce the list of items that she will need: soap, towels, and shampoo. Using a colon in this context effectively signals that additional information will be provided, which is the list of items necessary for her needs. This aligns with the grammatical rule that suggests a colon should be used after a complete thought when what follows elaborates on or lists out that thought. For the other choices, they do not follow this rule; for example, they either rely on incomplete clauses or do not clearly set up what follows the colon, making option A the only one that correctly employs the colon's function.
