As a rocket ascends, its acceleration increases even though the net force on it

Question

As a rocket ascends, its acceleration increases even though the net force on it stays constant. Why? (Assume a traveling distance small enough that the thrust, acceleration due to gravity and atmosphere do not change.) Which one below is correct?

The faster a rocket moves the more acceleration is imparted to it from a given force.

The rocket's mass decreases as its fuel is consumed. The same net force acting on a smaller mass results in a larger acceleration.

As the rocket ascends, fuel is burned at a faster rate resulting in a larger acceleration

.

As a rocket ascends it's momentum increases with it's speed. The greater the momentum of the rocket, the greater the acceleration imparted to it from a given force.

Explanation / Answer

because it consumes its fule and throws it in oppisit direction.. so by momentum conservation its speed increases in forward direction and it acclaretes..

"The rocket's mass decreases as its fuel is consumed. The same net force acting on a smaller mass results in a larger acceleration." is right
