Here are the essential concepts you must grasp in order to answer the question correctly.
Acidity and Basicity
Acidity and basicity are fundamental concepts in organic chemistry that describe the tendency of a substance to donate or accept protons (H⁺ ions). A stronger base is defined as a species that more readily accepts protons, while a stronger acid donates protons more easily. Understanding the relationship between acids and bases is crucial for predicting the behavior of chemical reactions.

Electronegativity
Electronegativity is a measure of an atom's ability to attract and hold onto electrons. In the context of basicity, atoms with lower electronegativity tend to be better proton acceptors, making them stronger bases. When comparing two bases, the one with the less electronegative atom is typically the stronger base, as it can more effectively stabilize the positive charge that results from protonation.

Resonance Stabilization
Resonance stabilization refers to the delocalization of electrons across multiple structures, which can significantly affect the stability of a molecule. In the context of basicity, if a base can delocalize the positive charge that results from protonation through resonance, it will be less basic. Therefore, when comparing bases, the ability to stabilize the resulting cation through resonance can indicate which base is stronger.
