Final answer:
Adolescents are about as likely to engage in oral sex as they are in vaginal intercourse, reflecting contemporary sexual behaviors and attitudes towards comprehensive sexual education.
Step-by-step explanation:
Regarding the question of which statement about oral sex and vaginal intercourse among adolescents is true, adolescents are about as likely to engage in oral sex as vaginal intercourse. The spread of sexually transmitted infections (STIs) and societal attitudes towards sexual education indicate that adolescents are engaging in sexual activities, including both oral sex and vaginal intercourse. Comprehensive sex education programs aim to teach adolescents about safer sexual practices, contrary to abstinence-only programs, which may not address the reality of teenage sexual behavior comprehensively. Therefore, based on current sexual attitudes among youth and education practices, it's reasonable to infer that both forms of sexual activity are prevalent among teenagers.
