Randomized multiple-choice question with dynamic drawing

A cannon ball with mass $m =3\rm\ kg$ is fired downward from a cliff at a height $h = 6.633\rm\ m$, at an angle $\theta = 21^o$ with respect to the horizontal, and an initial velocity $v_0 = 22 \rm\ m/s$, as illustrated in the figure below.

Suppose the ball hits the ground after $t = 0.61\rm\ s$. What is the distance from the base of the cliff that the ball hits the ground? Assume the acceleration due to gravity is $g=9.8 \rm\ m/s^2$.
