Can someone pls help me with this?

Answer:
C
Step-by-step explanation:
Lets go one step at a time.
This eliminates option A because, it continuous to speed up so therefore, option A is out.
This does eliminates a option. It eliminates D because, it says approximately the same speed however, D is too sharp and straight.
This one eliminates option B because, it says Brian only speeds up once and that was at the beginning so therefore, option B won't work
I believe C would be correct is correct because, there isn't any other option and it fits everything
Therefore, your answer would be C.
