Final answer:
The correct answer is option B. The second statement.
Step-by-step explanation:
The straw man fallacy in the given statements is the second statement: "Everyone is wearing that jacket, so it must be cool." The straw man fallacy occurs when someone misrepresents their opponent's argument and then attacks the misrepresentation instead of addressing the actual argument.
In this statement, the person assumes that because many people are wearing a jacket, it must be cool, without providing any evidence or logical reasoning to support their claim.
