The percentage of teens who stated that waiting until marriage for sex is not realistic is 60%.
Step-by-step explanation:
The correct answer is B) 60%.
According to the data from a separate survey, 65% of teens stated that they 'strongly agreed' or 'somewhat agreed' that although waiting until marriage for sex is a nice idea, it's not realistic (NBC News 2005).
