The developmental stage of adolescence is likely to be briefest in cultures where teens are select one:
a. egocentric.
b. seldom married.
c. experiencing role confusion.
d. financially self-supporting.

The correct answer is D. financially self-supporting. 
If teens are financially supporting themselves on their own, the developmental stage of their adolescence is likely to be briefer than with those teens who are still being supported by their parents or guardians. These teens mature much faster and learn the ropes of life by having to support for themselves rather than relying on adults for help.
