Why do you think that's the answer?

 

[jontyjashan]

because the motion of the bullet will be projectile so it would hit the target that is down

OK, but one thing that's not specified is how fast is the target falling?

 

[jontyjashan]

it has only been give in the question that it is falling
i also prepared a picture of it in the paint but was not able to upload it
if any1 is able to prepare the photo please post it
i will see if it is correct

 

[Doc Al]

I suspect the two choices were meant to be something like this:
(1) A kid fires directly at a stationary target.
(2) A second kid fires directly at a target that begins to fall under gravity the moment he pulls the trigger.
