The best option would be that the statements, "and the sooner the better!" and "it has to be!" all contribute to the speaker coming across as being "urgent", since these phrases are associated with impatience.
The statements, "and the sooner the better!" and "it has to be!" connote a sense of urgency, as if the author wants the actions depicted to occur now and not later, this is further conveyed by the use of exclamation marks in both phrases. So the correct answer would be option C: "urgent". Options A, C and D are incorrect because those statements don't convey a conversational tone, and they are not vague or indirect, quite the contrary.
