Here are the essential concepts you must grasp in order to answer the question correctly.
Oxidation Number
The oxidation number is a theoretical charge assigned to an atom in a molecule, reflecting its electron distribution compared to the isolated atom. It helps in determining electron transfer in redox reactions. For organic compounds, carbon's oxidation number varies based on its bonds with more electronegative elements like oxygen or less electronegative ones like hydrogen.

Electronegativity
Electronegativity is the tendency of an atom to attract electrons in a chemical bond. It plays a crucial role in determining oxidation numbers, as atoms with higher electronegativity, such as oxygen, will pull electrons towards themselves, affecting the oxidation state of adjacent atoms like carbon in organic molecules.

Steroid Structure
Steroids are organic compounds with a characteristic four-ring structure. Understanding this structure is essential for identifying the atoms involved in norethindrone. The arrangement of atoms and functional groups within the steroid framework influences the oxidation states of specific atoms, especially carbon, due to varying electronegativities and bonding patterns.
