The news reporter said, “Good reporting will always be appreciated by some.”
When using quotation marks for dialogue, the quotation marks must surround everything that is said - including punctuation. It is important to include all necessary punctuation marks that are used as part of the dialogue. In this case, the period is part of the dialogue as it signals the end of what the news reporter said and denotes it as a statement rather than a question or exclamation. Technically the third option also uses the quotation marks correctly as well. However, the comma is missing after the dialogue tag, and good should be capitalized.
