Answer: Option (b) is the correct answer.
Explanation:
The formula for formaldehyde is HCHO.
As the valency of Hydrogen is 1, carbon is 4, and oxygen is 6. It is known that hydrogen never forms a double bond with any other atom.
Hence, for carbon to complete its valency it will form two bonds with oxygen atom and one bond with each hydrogen atom.
Therefore, it can be concluded that only carbon and oxygen will form a double bond. So, option (b) is the correct answer.
