@All.

Option B is correct from my point of view.

Jet Propulsion: No propeller is used. Ejected gases from the nozzle produce thrust and follow Newton's 3rd Law. The propulsive matter is ejected within the propelled body.

Aircraft Propeller: In addition, a Propeller is used. This propeller causes the propulsive matter to flow around the propelled body.
