If a person's action is followed by a pleasurable consequence, the probability of that person repeating the same action increases. This best illustrates:

A) Heisenberg's uncertainty principle.
B) the Law of Effect.
C) generalization.
D) the Law of Desirable Consequences.

Law of Effect

A principle in psychology that states behaviors followed by positive outcomes are likely to be repeated, while those followed by negative outcomes are less likely to be repeated.

Pleasurable Consequence

A positive outcome or reward that follows a behavior, increasing the likelihood of the behavior being repeated.
