Beverly and Carl are in a race. Their graphs show the data.

Question illustration
A
Even though for a majority of the race they accelerated at the same rate, Carl won because his initial acceleration was greater than Beverly’s.

Even though for a majority of the race they accelerated at the same rate, Beverly won because her initial acceleration was greater than Carl’s.
C
Beverly accelerated at a greater rate for the entire race.
D
Carl accelerated at a greater rate for the entire race.
