Which statement correctly explains how a rocket is able to accelerate forward in the vacuum of outer space?
(a) The absence of gravity or friction allows the rocket to drift forward without needing any force.
(b) The rocket engine sucks in space and pulls the rocket ahead.
(c) The rocket pushes against the vacuum of space behind it to propel forward.
(d) Hot gases expelled backward exert an equal and opposite force on the rocket, propelling it forward.
