Jen's strong need for achievement is characterized by ________.

A) a desire to control others
B) a desire to achieve friendships
C) joy in accomplishment for its own sake
D) happiness with modest accomplishments

Jen's strong need for achievement is defined as a desire for personal accomplishment and success in challenging tasks, rather than a desire for control or friendship. This aligns with option C, joy in accomplishment for its own sake. Option D, happiness with modest accomplishments, does not fully capture the core of Jen's need for achievement. Option A, a desire to control others, is unrelated to a need for achievement, and option B, a desire to achieve friendships, does not accurately reflect the motivation behind Jen's need for achievement.
