Answer:
The correct answer is option D. Photographs of them reuniting with loved ones.
Step-by-step explanation:
If we think about the situation that climbers went through, and that they had to be rescued, and the fact that what they want to express is a sense of relief, the most appropriate option for this would be through Photographs of them reuniting with loved ones.
A biography that details what they lived, a news article explaining the risks of climbing mountains or a comment from a witness can only provide some information, and not the feeling of relief that mountain climbers experienced.
If we think of a critical situation like this, it is most likely that these people have thought about their loved ones all the time and if they would see them again. Therefore, showing a photo of that reunion would be the best option for the audience to see that relief.
