Lauren Was Excited to Go Shopping for New Clothes Before

 Lauren was excited to go shopping for new clothes before starting middle school, but she was surprised to find out that she suddenly needed to shop in the juniors section instead of the children's section. The most likely explanation for this change is that

A) Lauren is going through puberty, and her increased estradiol levels are changing the amount and distribution of fat on her body.
B) Lauren spent too much time over the summer eating fatty snacks in front of the television.
C) Lauren has been exposed to high levels of synthetic hormones, and she is beginning to go through puberty at an abnormally early age.
D) Lauren is going through puberty, and her increased levels of 5-alpha-reductase are changing the amount and distribution of fat on her body.
