The base dissociation constant, Kb, is a measure of the degree of dissociation, or ionization, of a base in solution. It provides a quantitative measure of the strength of a base in solution.

A large Kb value indicates a strong base because it means the base ionizes to a large extent in solution. Conversely, a small Kb value indicates a weak base because it means the base ionizes to a small extent in solution.

In the case of CH3NH2, the Kb value is 4.4 × 10^-4. This is a relatively small value, indicating that CH3NH2 does not ionize completely in solution and therefore is a weak base.

So, the correct answer is B. CH3NH2 is a weak base.
