Arocket burns fuel to produce thrust, the force that moves the rocket forward. select the best answer from the choices provided
a. true
b. false

We, you're certainly on the right track, but the thrust is
not always directed forward.  If you want to slow the rocket
down for re-entry from orbit, or for a soft touchdown, then
you need to direct the thrust backwards, that is, opposite to
the direction in which the rocket is moving.
