A group of friends get together to plan a vacation that will allow the expression of their personalities. They are all high in conscientiousness and low in extraversion.
Based on the Big Five model of personality, as reviewed during discussion sections, one predicts that the plan they develop will let them:

a) be energetic and sociable, as well as less structured and more impulsive.
b) be well-organized and structured, but will include lots of opportunities to meet people.
c) be very unstructured and casual, like going to a people-free beach to commune with nature.
d) be well-organized and structured, but it won't include a lot of opportunities to meet new people.

D.

Explanation:

The Big Five Factors of personality trait was developed by Robert McCrae and Paul Costa in 1987. But their theory is developed on the previous theories of personality traits by Fiske, Norman, Smith, etc.

The Big Five model describes five personality traits that develop a person's character.

According to the Big Five model, conscientiousness measures the level of goal-directed behaviors and thoughts. A person with high conscientiousness is organized, is goal-oriented, and pays attention to minute details.

Whereas, an extraversion measures the level of socializing, excitement, and emotional expression. A person with low extraversion will have the characteristic of preferring solitude over socializing, are difficult in communication, and avoids being the center of attention.

So, from the given options the plan that matches the criteria is option D. The criteria given is that all people in the group are highly conscientious and low in extraversion. So, they will be organized and structured but will be reserved for the opportunity to meet and talk with new people.

Thus option D is correct.
