Answer: Hi there! This question is a little tricky for me, but I think that your answer would be B.
Explanation: I don't know much about snowboarding, but I can infer that this "marvel" of technology is likely new and revolutionary in the snowboarding world. Additionally, a "reverse camber" has something to do with snowboarding jargon, so adding this sentence would benefit a lot of readers, which is why I selected the second choice as my final answer.
Sorry that I couldn't give much of a definite answer here. I hope you have a good day!
