What are the top 3 derivatives?

Could you please enlighten me on the top three derivatives currently available in the financial market? I'm particularly interested in understanding their functions, their popularity among investors, and any potential risks associated with them. Additionally, it would be helpful if you could compare and contrast these derivatives with other financial instruments to provide a broader perspective. I'm seeking a comprehensive yet concise overview to aid in my understanding of this complex topic. Thank you in advance for your insights and expertise.
