Thomas Is an Excellent Salesman and Would Like to Be

Thomas is an excellent salesman and would like to be considered for the higher paid positions in the company.

In fact, rather than taking a flight, Thomas drove three days just to go to his brother's wedding, and he missed the annual family reunion because he did not have time to drive there. Thomas' behavior would best fit which definition of abnormality?

A) deviant
B) personally distressful
C) interactional
D) maladaptive
