Which statement best describes teenage sexuality according to the material?

• A. Teens are scared of STDs, so early sexual activity in teens has declined lately.
• B. Teens are not concerned about STDs
• C. Teenage sexual activity has increased
• D. STDs do not affect teen sexuality

Answer: (A)

Perceived risk of STDs shapes teenage sexual behavior. When teens are aware of STDs and fear the consequences, they’re more likely to delay sexual initiation or practice safer choices, which can lead to a decline in early sexual activity. This matches the material’s point that concern about STDs has contributed to fewer teens engaging in sex at younger ages. The other statements don’t fit as well: some teens are indeed concerned about STDs, trends aren’t typically described as a clear rise in teenage sexual activity, and STD risk is a factor that influences teen sexuality rather than being irrelevant.
