Answer:
c. just under 50%
Step-by-step explanation:
Just under 50% of teenagers over the age of 14 admit that they have had sexual intercourse. In the United States, people often have their first sexual encounter during their teenage years. However, obtaining accurate numbers of this phenomenon can be difficult because such behaviour is still stigmatized in many social groups. Therefore, it is likely that the number of self-reports is different from the real number of cases.
