Answer
The correct answer is: (d)
Work Step by Step
We can find an equation for the vertical position as a function of time:
$y = v_{0y}~t+\frac{1}{2}a_y~t^2$
$y = -4.9~t^2+v_{0y}~t$
This is the equation of a parabola that is concave down. Note that $y = 0$ at time $t = 0$.
The correct answer is: (d)
