Solution
The correct answer is: Carboxylic acids with long carbon chains of 12 to 20 atoms.
Fatty acids are carboxylic acids with long carbon chains. The carbon chain length can vary, but most commonly contains 12 to 20 carbon atoms. This structure makes them nonpolar and hydrophobic (water-repelling). They are a key component of fats in our diet and in our bodies.
