Answer:
B. dark matter
Explanation:
The<u> current theory</u> is that the dark matter composes about 85% of the matter in the whole universe, possibly in large majority made out of unknown material. What we found so far is that the majority of the dark matter is NOT composed of baryonic material (the stuff that makes stars and planet).
We know dark matter exists and we suppose there's a HUGE amount of it that fills the gaps between stars and planets.
Acceleration = (Vf - Vi)/t
Since Vf= 60m/s
Vi= 15m/s
T= 15s
=> a= (60m/s - 15m/s)/15s
= 3
So the acceleration is 3m/s^2

Hope this Helps!
Using the "v = f. λ" <span>equation...
Your "v" or </span>velocity = 156.25 meters/second
