An object moves along the \(x\)-axis. Its position \(x\) as a function of time \(t\) over the interval \(0 \le t \le t_3\) is shown in the graph. The curve starts with a horizontal tangent at \(t = 0\), has an inflection point at \(t = t_1\) where the concavity changes from upward to downward, reaches a local maximum with a horizontal tangent at \(t = t_2\), and continues downward through \(t_3\).

Which of the following graphs best represents the object's velocity \(v\) as a function of time \(t\) over the same interval?
