Final answer:
Danger Sense grants a barbarian Advantage on Dexterity saving throws against traps and spells, which is option C among the given choices.
Step-by-step explanation:
The ability of Danger Sense that a barbarian gains in the game of Dungeons & Dragons provides a specific combat advantage. According to the rulebooks, Danger Sense enhances a barbarian's reflexes and ability to dodge away from certain types of harm. Specifically, when you look at the options provided in the question:
- A) Advantage on initiative rolls
- B) Proficiency in perception checks
- C) Advantage on Dexterity saving throws against traps and spells
- D) Resistance to poison damage
We can determine that the correct answer is C) Advantage on Dexterity saving throws against traps and spells. Barbarians with Danger Sense do not naturally get advantages on initiative rolls, proficiency in perception checks, or resistance to poison damage solely through this ability. Therefore, the benefit they do receive is specifically related to Dexterity saving throws when evading traps and spells, which signifies their keen senses alerting them to dodging out of harm's way in such situations.
