Trampoline is dangerous to some extent. In order to increase safety, pressure sensors can be installed on the elastic net, and the robot can simulate and record the athletes' movements.
As can be seen from the figure, the longest time for an athlete in the air is: t = 3.3s-0.9s = 2.4s.

Athletes throw vertically, so the maximum jumping height is:

H= 12g(t2)2, which brings t=2.4s into: h=7.20m, so ABD is wrong and C is right.

So choose C.
