The list of choices you included doesn't have any correct expressions on it.

- - If the rocket went straight up, and then dropped back at the same place

it was launched from, then it must have dropped straight down.

- - The route it followed on the way down was exactly the same as the

route it followed on the way up.

- - Since it reached a maximum height of 150-ft from the ground

and the route was straight, the length of the route was 150-ft.

- - (150-ft going up) plus (150-ft coming down) = 300-ft traveled all together.
