Response B is better because it correctly identifies the visible icon (dark hooded helmet with red glow and quantity “1” in the corner) as the Satanic item from Dota 2, while Response A wrongly identifies it as a Dead by Daylight throwing-knife icon. B therefore accurately answers “what is this”.

Response B provides a more accurate identification by correctly recognizing the visible icon as the Satanic item from Dota 2, which shows a dark hooded helmet with a red glow and has the number "1" displayed in the corner. In contrast, Response A incorrectly identifies this same icon as a throwing-knife from Dead by Daylight. Since Response B properly answers the question "what is this" with the correct identification, it delivers a superior response.
