B. Is the correct answer, however if this happens over a long period of time, it will develop into C.

In this given problem, to solve for the acceleration we have to
assume that the acceleration is constant. This assumption helps us understand
that the velocity of Dave follows a linear increase and hence we can use the
formula below for calculating the acceleration:
a= (Vf – Vi) / t
where
Vf = final velocity = 7.0 m / s
Vi = intial velocity = 3.0 m / s
t = time elapsed = 10 s – 5 s = 5 s
Substituting the known values into the equation:
a = (7.0 m / s – 3.0 m / s) / 5 s
a = 0.8 m / s^2
Answer:
<span>D. 0.8 m/s2</span>
By the time they are 12 years of age.
Hope I helped!!
Giving me brainliest answer helps a lot and is very appreciated =)
Secondary sex features are characteristics that develop during puberty. Using the process of elimination, options B and D are really primary gender characteristics. Also, option A has more to do with your genetics than your gender.
That leaves option C. Breasts. They are a secondary sex characteristic that develops during puberty.
Hope this helps! :)
