Read the following evidence.

Teens who participate in summer camp:

• Develop independence, spending most of their time with peers and unfamiliar, though trusted adults.

• Reap the physical benefits associated with fresh air, plenty of exercise, enforced activity, and regulated meals.

• Make great strides in self-confidence by being on their own and being constantly challenged with new activities.

Which claim correctly synthesizes this evidence?

A.
These three positive outcomes can be as much attributed to teens’ own abilities and determination as to the situation.
B.
There is a direct connection between health and self-confidence, though not necessarily between independence and either factor.
C.
Meeting challenges without parental support leads to independence, and camp bolsters this by contributing to campers’ health.
D.
The structured environment that fosters an active lifestyle is as helpful as the freedom campers experience in a semi-controlled environment.
