Which of the following statements correctly describes the relationship between hybridization and basicity in nitrogen heterocycles?

If a nitrogen atom is sp2 hybridized, what is the percentage of s character, and how does this affect its basicity?

Using Huckel's rule, determine the aromaticity of pyrrole and its impact on basicity.

Given the pKb values of imidazole (7.0) and pyridine (8.77), what can be inferred about their basicity?

Given the pKb values of pyridine (8.77) and pyrrole (13.6), which statement accurately describes their relative basicity?
