Hey there!
The second option or option B seems like the best.
B. Young people who participate in first sexual intercourse before age 14 are significantly more likely to have more sexual partners throughout their lives.
Hope this helps!
Flirting is doing something to attract someone else. For example, you would flirt with your crush. Footsie is an act of flirting (I think of it like a game) where you touch another person's feet and legs with your own under a table secretly.
I don't really know how it affects society, but if done in a relationship, I guess it shows signs that you appreciate your lover. (This is my guess, I've never dated before)
For moderate-intensity physical activity, a person's target heart rate should be 50 to 70% of his or her maximum heart rate. ... For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 – 50 years = 170 beats per minute (bpm).
Brainlest would be appreciated, have a great day.
