Question restatement: Which of the following is true of the relationship between exercise and adolescence?

Option A: In adolescents, exercise lowers the incidence of type I diabetes. This claim is not well-supported as a direct causal relationship between exercise and reduced incidence of type I diabetes in adolescence is not strongly established in the literature; Type I diabetes has autoimmune features, and while exercise has many health benefits, stating it lowers the incidence of Type I diabetes overstates the evidence.

Option B: Individuals become less active as they reach and progress through adolescence. While activity levels can fluctuate and some cohorts show declines, this statement overgeneralizes and isn’t universally true across all populations or contexts; it also doesn’t capture the complexity of how activity relates to adolescence overall.

Option C: Memory is the cognitive factor that improves the least through exercise in adolescence. This is a specific claim about cognitive domains; research on exercise and cognition shows improvements in several areas (e.g., executive function, attention, processing speed) during adolescence, so singling out memory as the least improved is not robustly supported and likely inaccurate.

Option D: Male adolescents' physical activity is associated with their male friends' physical activity. This option aligns with social-ecological findings that peer behavior, especially among same-sex peers during adolescence, is associated with an individual’s activity levels due to social norms, access to similar opportunities, and encouragement.

Analyzing each option step by step:
- Option A attempts to connect exercise with a reduced incidence of Type I diabetes, but the causal link is not well-established in adolescence; therefore, the statement is not reliably true.
- Option B asserts a universal trend of decreasing activity through adolescence; while some groups show declines, this is not a universally true or defining relationship and ignores variability by gender, culture, and environment.
- Option C makes a broad claim about memory; existing evidence shows various cognitive domains can be influenced by exercise, and declaring memory as the least improved domain is unsupported and overly narrow.
- Option D cites a peer-influence relationship, which is consistently observed in adolescence: friends, especially male peers for male adolescents, tend to have correlated activity levels due to shared social contexts and opportunities.

In summary, among the options, the most defensible statement about the relationship between exercise and adolescence is that male adolescents’ physical activity is associated with their male friends’ physical activity, reflecting peer influence patterns commonly reported in adolescent health research.
