B. Suspenseful
Step-by-step explanation:

Creating suspense allows the reader to experiment feelings of empathy, reader concern and provide the settings for impending danger and escalating tension. In this case the phrase "ruthless and utter destruction" creates suspense because of not knowing exactly how the destruction methods would be, but we know they are ruthless.
