The "Off-Time Hypothesis" Suggests That

The "off-time hypothesis" suggests that

A) pubertal physical changes are not continuous, but rather are very "stop and go" because the hormonal releases that mediate such changes have "off" and "on" periods.
B) when a girl experiences puberty earlier than average, it interrupts her later-life reproductive potential, since her eggs will be "older" when it comes time to attempt pregnancy.
C) boys do not have a traditional "on-time" period of pubertal change, which explains why developing earlier or later than the average peer brings with it no negative consequences for boys.
D) both early and late physical development is stressful for boys, who prefer to be "on time" in their physical development.
