The correct answer is letter C. In the passage from “The Rescue Mission”, the author has chosen the present tense to make the narrative appear more vividly by assimilating it to the here-and-now of the speech act. This use of the present tense is also called Conversational and Narrative Historical present. It describes the past as if it is happening now. These sentences are clear examples of this use in the setting: “I’ve got the clips, bungee cord, vests, and basket, and the rest of the equipment is onboard.”; “I have to get my head in the zone because this chopper is heading into stormy conditions, and it will feel as though things are happening at supersonic speed when we get to the site.”
