- C. Middle of the chain
- D. Both out of the chain and middle of the chain
Explanation
Formyl is the aldehyde functional group. Removing the R group from an aldehyde gives us the formyl functional group i.e. ―CHO. Hence, it is always at the end of the chain or 'out of the chain'.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
