Final answer:
A molecule with a degree of unsaturation of 0 has no double, triple, or aromatic bonds, which means it is fully saturated and only contains single bonds.
Step-by-step explanation:
A molecule with a degree of unsaturation of 0 indicates a fully saturated molecule, meaning it has no double bonds, triple bonds, or aromatic bonds. Therefore, the correct answer is B. Double bonds, C. Triple bonds, and D. Aromatic bonds. Organic compounds that contain one or more double or triple bonds between carbon atoms are described as unsaturated, with alkenes having double bonds and alkynes containing triple bonds. Saturated hydrocarbons, on the other hand, only contain single bonds and the maximum number of hydrogen atoms bonded to the carbon atoms.
