Final answer:
The cause described, attributing Caleb's lateness to his laziness, is an example of a dispositional cause.
Step-by-step explanation:
The cause described in the scenario, where Caleb's friends attribute his lateness to his laziness, is an example of a dispositional cause. Dispositional causes refer to internal factors such as personal traits, habits, or temperament that influence behavior. In this case, Caleb's friends are attributing his lateness to his inherent laziness rather than considering external factors that may be causing the lateness.
