Solution

The correct option is D A walks faster than B
In this graph position and time are the parameters.

Option A is correct statement, as the slope of A is lower than B.

Option B is also a correct statement, because the speed of A is less than B, so A must have started before B.

Option C is an incorrect statement as A is slower than B.

Option D is a correct statement as both graphs are ending at the same time.

Thus the correct answer is C.
